Aliens vs Predator 2 singleplayer custom map titled "Ivan1".
Map author: OO-Edds
The first of OO-Edds' Ivan maps. Some of the level design is a bit boxy, but it is overall good. The map is primarily human vs human with only a tiny bit of predator fighting. Make sure you crouch when crossing the bridge at the start of the map.
I also blow myself up by accident in this playthrough lol.
