I think you'll need to explain a bit better.Do you mean a gamemode like MGS? Bots that, when they detect you, trigger an alarm so all bots attack you like in MGS? Or maybe a real player based MGS gamemode?

I tried to make this is in the form of a Payday 2 stealth gamemode for blockland but the scope of the project required bot pathfinding and this was 2016 when that technology wasn't really explored so I dropped itI'm sure top down mgs gamemode could work nicely but otherwise an fps stealth game would require some form of radar or through wall enemy tracking. Not that feasibleWith bot pathfinding most of the development becomes trivial. Without it the game cannot function properly
