One my favourite Xcom games,
This review is from: X-Com Apocalypse (Video Game)
This was the final Xcom game in the old series and to be honest is probably my favourite (much better than the new ones!). Although the weapon usage isn't as good as the others, the overall feel and strategies required are quite good.
It is set in a city state where the aliens have come to play. Cue lots of exploratory missions and then massive battles as you find some weird looking creatures. The whole view is on a smaller scale than the earlier ones, so you might need your glasses!
