Radian Simulations, the studio behind the Cold War tank simulator Gunner HEAT PC, has banned all generative AI content from its official community spaces. The studio announced the rule in a pinned post on the game’s subreddit. It covers mods, art, video thumbnails and text summaries made in whole or in part with AI tools.
The ban extends a policy already in force on the game’s Discord server. Radian Team now plans to enforce it on every forum it officially runs, and the post makes no exceptions.
What the Gunner HEAT PC ban covers
According to the subreddit post, the rule applies to any material “created in whole or part by generative AI.” The developers list text summaries, image edits, art, animated clips, video thumbnails and game mods based on Gunner HEAT PC as examples. The list is not exhaustive.
Radian Team framed the decision as a matter of principle. The studio says the ban is “in keeping with Radian Team’s values” and exists “to uphold the integrity of interactions in this community.” The post goes further, stating that generative AI output has “no place in our world, and we have no respect for them.”
Modding is one area where the policy could have a visible effect. DualShockers reports that quickly assembled, vibe-coded mods have made it harder for more polished community packs to find an audience. The zero-tolerance rule aims to stop that from happening around Gunner HEAT PC.
A niche tank simulator in early access
Gunner HEAT PC is a modern armored combat simulator set in a fictional late-1980s conflict where the Cold War turns hot. The game is in early access on Steam and runs only on PC.
Radian Simulations aims for accurate ballistics and vehicle physics while keeping the controls playable without extra peripherals. As a result, the game sits between arcade-leaning titles such as War Thunder and World of Tanks and study-level simulators like Steel Beasts. For a team built around historical and technical accuracy, AI tools that produce confident but wrong details about armor or ammunition are an obvious problem.
Wider pressure on indie games
The announcement lands during a difficult week for indie developers on Steam. According to Eurogamer, the October 2026 Steam Next Fest has roughly twice as many demos as the June edition. The event runs until October 26. DualShockers points to generative AI tools as a likely driver of that growth.
Valve requires developers to disclose AI use on their store pages. However, DualShockers notes that many games on the platform use AI tools without that disclosure. Even with disclosure, the volume of low-effort and copycat releases makes it harder for small teams to get noticed.
Some developers are now pulling demos entirely. The team behind Drunken Goddess Reflux cancelled its public demo over fears that “the demo’s content could be used to quickly imitate or replicate the game’s presentation and gameplay with AI or other tools.” DualShockers reports that other studios have made the same call for the same reason.
Gunner HEAT PC remains in Steam early access. Its new policy now applies across the subreddit, the Discord server and any other community space Radian Team officially maintains.
