Space Hulk (1993): Deathwing Campaign 11: Descent 

This is the eleventh mission in the Deathwing Campaign. The map has some annoying twists, but thankfully the genestealers do not spawn in too large numbers. The Assault Cannon ran out of ammo, and I didn't even notice. It was just pure luck that all the genestealers in front were taken out with the final shot.
The objective is simple, just move to the teleport area.
Played in DosBox on Linux.
