Von_Kalev: I'm about to give up on this fucking battle. Even when destroying one of the spider tanks it seems like suddenly my characters have horrible aim and in a matter of turns more enemies swarm in, making it impossible. Up to this point this has been a great game.

pleasenoname: there is also computer stations that shut the tanks down, and stop working after you use them. One on the north of the room and one on the south.

A spell to destroy armor is really helpfull in this battle, as well as medkits.
