What was this game?

[Lando]

It was the first game I played on the Amiga.  A 2d turn based strategy game.  You took a team of space marine types, with different units having different weapons, and moved gradually from the left to the right, where the aliens were advancing from.  Graphics were simple, terrain was mostly grass, the odd bush and a few buildings and obstacles where one could position snipers.  You had to get your team well set, because when the aliens advanced they came on brutally strong and could wipe you out in a few turns.

Anyone remember this?

Cheers!

I think it's X-Com: UFO Enemy unknown
