Understanding your viewers is essential to a video games success and figuring out how that viewers engages along with your recreation may be extremely essential to retaining and satisfying gamers. If gamers are having a tough time discovering the enjoyable in your recreation, then they’re prone to look elsewhere.
On this visitor publish, Azur Video games lead analyst Alexey Platonov explains how heatmaps are underused in video games growth however ought to be used extra typically as a instrument to realize a visible illustration of participant engagement.
Downside areas are magically uncovered and may be corrected and easy quality-of-life enhancements can create the very best expertise potential. Here is how.
Heatmaps are an intriguing and helpful analytical instrument, but they’re surprisingly underutilised, even by main PC and console recreation builders. Within the context of cellular video games, their utilization is even scarcer.
After I say heatmaps, I am referring to a visible illustration of participant actions and coordinates: pathways navigated throughout a map, factors of consumer interplay, sniper positions in shooter video games, difficult trajectories in numerous places, and so forth.
Heatmaps actually shine in mid-core tasks. We often use them in hyper-casual video games, however we’re extra centered on UI/UX evaluation. The primary utility of this instrument is to establish potential enhancements in stage design. This ensures {that a} recreation’s progress is not unexpectedly hampered by some non-obvious parts (like useless ends). Heatmaps can help in enhancing metrics, visualizing weak factors, and saving builders each time and substantial testing bills.
So how does it work? We obtain analytical occasions from the sport, together with the participant’s coordinates at particular cut-off dates and what the participant is doing at these moments. This info may be overlaid onto a stage map – often taken as a typical screenshot in Unity or Unreal Engine – and permits for an examination of consumer actions and but in addition the frequency of various occasions at numerous factors on the map. You possibly can see an instance of this beneath.
Our first expertise
Our maiden enterprise into heatmap utilization occurred about 2.5 years in the past with our mid-core on-line PvP shooter, World Battle Heroes.
When a brand new map was launched within the recreation, we together with our stage designers puzzled about its precise stability. We initially carried out testing on a small group of gamers and detected a big win price benefit for one aspect. This prompted us to confirm our findings utilizing heatmaps. We had been additionally wanting to visually grasp participant motion, the places of most kills, the websites of frequent shut fight, sniper positions, and many others.
The factor is, not all points are readily obvious from uncooked numbers. An analyst’s function is not only about gathering these stats but in addition discovering options and generally even figuring out the issue itself, which could not be apparent to everybody else. This requires product data, creativity, and impartial considering.
So, our preliminary use of heatmaps was an experiment to see if this instrument may spotlight one thing that we or the sport and stage designers could have missed.
As an illustration, here is a slender spot the place gamers steadily died.
And this heatmap marks all of the kills made with sniper rifles. It confirmed the extent designers’ preliminary assumption that the homes on this map are the very best spots for snipers.
Because of this, we found that heatmaps are a potent visible instrument price using in future. Furthermore, the preliminary implementation took only a few days, and subsequent analyses utilizing heatmaps may very well be carried out inside hours.
Our key takeaways after this preliminary evaluation had been:
1. Gamers utilised all potential routes throughout the map.
2. Gamers gravitated in direction of routes nearest their spawn factors.
- This led to some routes being underused, and a diagonal exercise focus from the respawn factors.
- These less-traveled routes weren’t ideally suited for putting ammo and/or medkits.
- Participant exercise may very well be redirected to underused routes by adjusting spawn factors nearer to those routes.
3. The left half of the map (crew B’s zone) noticed extra exercise, offering a bonus to crew A.
- The home on crew B’s aspect was barely bigger and it had a bottleneck (between the home and the fence) the place a lot of the kills and motion occurred.
- Within the open check information, crew A demonstrated the next win price than crew B (55% to 45%).
4. Gamers from each groups had been extra inclined to remain in their very own half of the map than to enterprise into enemy territory.
5. The simplest weapons for this map had been assault rifles, machine weapons, and sniper rifles.
- Assault rifles had been greatest suited to open areas (principal streets and bypasses).
- Sniper rifles had been ideally suited for in-house use to take care of distance.
- Machine weapons proved efficient each in open areas and indoors.
After WWH, we utilized heatmaps in just a few extra shooter video games, the place they certainly revealed some clear points with map stability. In fact, not each challenge advantages from this methodology, as core mechanics and general challenge look & really feel nonetheless take priority. Nonetheless, analysts can use these instruments to search out alternatives for progress so {that a} good challenge would not lose gamers as a result of less-obvious points.
The next case completely illustrates this level.
Enhancing gameplay with heatmaps
Considered one of our mid-core tasks, Off Street – an off-road driving simulator that options handbook gear shifting, differential locks, and comparable parts, drastically benefited from heatmaps.
This challenge did not initially yield excessive metrics, and typical funnel analytics confirmed us that many gamers had been quitting in the course of the tutorial. This type of behaviour often signifies an off-target viewers or technical points inflicting recreation crashes at launch. Nonetheless, neither of those gave the impression to be the case right here. No clear purpose for participant drop-off may very well be discerned from these funnels alone.
So, we determined to analyze the place gamers had been encountering difficulties and introduced heatmaps into play.
Provided that Off Street is a simulator recreation offering a level of free motion, the heatmaps rapidly revealed cases the place gamers had been heading within the flawed route, getting caught, and finally abandoning the sport. It turned clear that the position of checkpoints on the map was inflicting confusion, with some gamers merely not understanding the place to go. The extent design was inadvertently main them astray.
We then used the participant routes from the heatmap, launched the sport, and adopted these paths ourselves, which made the issues click on into place.
Here is a hanging instance.
The screenshot depicts the participant’s perspective of the extent. The purple arrow factors to the checkpoint – the participant’s goal – whereas the white arrow and blue line illustrate the proper path to achieve this checkpoint. Nonetheless, 24% of the gamers noticed the goal, drove straight in direction of it, obtained caught, and stop the sport out of frustration. In any case, why take a detour in an off-road simulator, proper?
From a stage design perspective, potential options may embrace obscuring the checkpoint with a mountain to forestall it from diverting gamers from the proper path or inserting indicators to information gamers. An skilled product analyst, accustomed to how the product features, can readily suggest these hypotheses.
Furthermore, this type of visible evaluation through heatmaps is well interpreted and gives clear indications of what and the place enhancements may be made – insights that would not be gleaned from numbers alone. Because of this, even a minor adjustment to the tutorial boosted the Day One retention price by three proportion factors. That being mentioned, numerous different complicated enhancements had been nonetheless crucial.
The sport is now up to date frequently with a wealth of content material, so heatmaps are frequently in use. Whereas there isn’t any win price stability right here, the sport drastically depends upon how the gameplay is acquired by the gamers, necessitating constant remark of participant conduct in numerous environments.
Taking a look at conventional numbers alone, we would not have been in a position to attract the identical conclusions, nor make recreation modifications as swiftly

Technical issues for accumulating analytics
Once we initially used a heatmap for World Battle Heroes, we bumped into a number of issues that might be helpful for anybody planning to make use of this instrument.
The primary level was that WWH was already sending us a big quantity of analytical information. We needed to have all gamers ship their places each 5 seconds to attain most granularity within the coordinates of participant actions. Nonetheless, once we evaluated the potential progress within the variety of occasions, the dimensions of the database, and the frequency of queries, it turned clear that inundating the information with coordinates was not an optimum answer.
After a lot deliberation, we settled on two alternate options.
The primary method concerned sending occasions to a sure proportion of gamers (round 10%). Nonetheless, the sheer quantity of gamers was nonetheless too excessive (even once we tried to decrease the proportion), main us to desert this selection.
The second method turned viable when the WWH crew utilised beta testing extensively. They’d a separate server with a core, engaged viewers that had first entry to new maps. This labored remarkably properly. With a smaller participant base, we may afford to ship the required occasions to everybody each 5 seconds. I extremely suggest this methodology.
For Off Street, we additionally moved in direction of this second method. The choice wasn’t influenced by the style of the sport however by the dimensions of the challenge. If the challenge grows and the participant base expands, the variety of occasions despatched can turn into overwhelming. Utilizing separate servers for beta testing not solely helps handle this difficulty but in addition permits us to shine the maps previous to a full replace launch.
One other minor complication includes the scaling and overlay of heatmaps on the extent screenshot. Whereas the screenshot is simple to seize throughout the recreation engine, it is tougher to align the transmitted coordinates with the screenshot, accurately modify the size for readability, and select the suitable angle. At occasions, I discovered myself recalling lectures on analytic geometry and algebra.
Whereas this is not precisely a technical difficulty, there will definitely be some tweaking of the dimensions sliders. It is often a bit tough the primary time round, but it surely turns into simpler with apply.
At the moment, we’re experimenting with animated GIFs that visually display participant motion (both individually or collectively) throughout the map. Nonetheless, these are extra beauty enhancements.
Improvement
Our crew created the heatmap instruments with only one lead and some further contributors. Now, the system is in place and accessible to all. The one caveat is that deciphering the ultimate information requires not simply the talent to construct heatmaps but in addition product experience. It is essential to have the ability to decipher the information your self slightly than merely handing over uncooked graphs to recreation designers.
It is helpful when analysts can suggest hypotheses, interpret what they see, and recommend options to different departments; that is extremely valued.
Relating to the preliminary growth of the instrument, creating occasions on the consumer aspect is simply a few hours work for a programmer, together with the time to seize an appropriate stage screenshot.
The primary work lies with analytics. Over the course of the experiment, we added performance in a number of iterations, enhancing the readability of the maps to make sure the instrument may very well be successfully used sooner or later. We accomplished this in per week, excluding the wait time for an replace with new occasions to be launched. In whole, it took about two weeks.
Now, the entire technique of accumulating and analysing information takes merely 1-2 days to course of all the pieces, confirm that the information is coming in accurately, and test the information itself. One further day is required to attract conclusions.
Returns
When it comes to returns, the usage of this instrument has been totally worthwhile. Taking a look at conventional numbers alone, we would not have been in a position to attract the identical conclusions as we did with Off Street, nor make recreation modifications as swiftly.
As for alternate options, maybe you may have a considerable crew of QA specialists. And in case you do not? One choice may very well be hiring third-party testers who report their gaming classes. Nonetheless, not all of them possess product data, so analyzing the footage and figuring out patterns can be time-consuming (to not point out pricey).
Ideally, an analyst ought to have the ability to save time for the QA division, stage designers, and finally, the whole crew, thereby boosting their productiveness.
The best energy of an analyst lies not in number-crunching however of their means to say, “it really works this fashion, so let’s do this and anticipate these outcomes.” For a junior analyst, mastering the instruments and laborious expertise is important. However a senior analyst operates at the next stage, tackling issues with unknown options. They discover a technique to resolve them. Heatmaps are a precious instrument for this goal, significantly when different strategies fall quick.
