InSanity is psychological horror, total conversion mod for DooM 2. You play as Polish policeman who started losing his mind. At first he had horrible nightmares but now... Nightmares become truth...
GzDooM OpenGL effects.
New sounds and Soundtrack.
Whole scary story.
Steam, original, BFG IWAD compatibility.
A little bit of Gz/ZDoom movement usage (jumping, crouching, freelook).
And much more in future (I wish).
Current version - Alpha 1.05
Next version --> 06.06.18
