Ah, good old X-com. I love that game. I still have it on my harddrive somewhere. I love it so much I even wrote two short fan fics of it starring Sergeant Ironhead.
I've got so much good memories there.
First encounters with a Chryssalid. I was still using bullets. My whole squad got zombified by one alien.
Or my first test run with a new weapon the light bulbs called a Blaster Bomb launcher.
,,Hmm, I heard that this thing can even punch through the outside wall of an ufo. Time to try it out on that battleship, those alien scumbags will be surprised when I drop through the roof right into their bridge instead of taking the door. I'll put my troops on the roof, but far enough away to be safe from the blast."
*Bomb comes flying from the other side of the battlescape, makes a few circles and dives into the ufo's roof. My whole squad dies exept for the guy who was sitting on top of the transport on the other side of the area with the launcher in his hands.
,,Oops, the blast radius was a bit bigger than expected."
Really, if you find it in a garbage bin, buy it! X-com is the god of tactical squad-based warfare!
