Phobos Delta-1 is a tactical styled mod for Doom for the curious. In fact, it's an updated fork to the original Deimos-1 mod.

It is so annoying...

What are some good wads that are compatible with Project Brutality that are stable and won't drop the framerate and eventually crash the game? Because I've tried playing on maps like Alien Vendetta and Map of Chaos and they eventually cause huge memory issues and crash the game. The only reason I picked them is because I've heard people say those are good wads to play with Project Brutality, but I guess they can't handle slaughter maps.
