Hello there!
After some years I decideed to return to this after finishing the new xcom and xenonauts. Compared to them, this is a grittier, less merciful and more hardcore science fiction (I'm not even going to say how XCOM's new game lacks in anything scientifically)
But, well... ahem.
I killed all the aliens and... well, the combat doesn't end.
I hope you have a console command that lets me win or just to make sure, all aliens are dead. Do you?
