[quote="b0rsuk":1nfc39sh]Does memory fail me ? I thought rad suit used to negate all damage from lava or acid in DooM.
Not quite. In Vanilla Doom with the rad suit on the -10/20 % nuke floors should hurt "occasionally", somewhat in random, but not at constant rate.
There's yet a third -10/20 % nuke floor, the one at the end of Doom E1M8. It strips the rad suit and exits when health is too low. Wonder if it's behaviour has been mixed with types 4 and 16 floor types?
