Re-release of ROOM with a spicy extra feature: Berserk powerup now works for whacking Doomguy's head with the fist!
Recommended to play with So Doom source port, version 7.0.0 Github.com
Command line: so-doom -iwad doom2.wad -merge room_berserk.wad -deh room_berserk.deh
Luckily the way to fix the game sometimes freezing with the fist was described here Doomworld.com,
the MF_NOBLOCKMAP flag was to be applied to BFG projectile and rocket that are used in player's attacks on himself.
