Strife: Accidental Exploit
Monsters in Doom generally start the game in a dormant state. Only when you make them aware of your presence — by walking where they can see you, or firing a weapon where they can hear you — do they start moving around and attacking. The saved games apparently don’t record information about which monsters are dormant and which are active. When you reload a saved game, all monsters reset to dormant. It’s sometimes possible to exploit this to make the game easier, but this is obviously cheap.
Now, for all I know, Strife may not share this bug. Or perhaps it did originally, but not when played under ZDoom. But maybe it does. I haven’t been exploiting it deliberately, but there’s a section where I might have triggered it accidentally. I’m just not sure.
It’s harder to tell in Strife because the rules are more complicated. If I sneak into a high-security area wearing an enemy uniform, I can generally walk past the guards unnoticed. Eventually, I encounter something that isn’t fooled by the disguise. If I fight it, save the game, die, restore, and walk past the same guards again, I don’t know for sure if they’re still docile due to the bug or if it’s just because they never got woken up.
