This is what I think the level is like: Single storey war-torn building. plenty of grunts. one maybe two apache helicopters. NO aliens lots of corners to hide in etc.
This could be from HL, OP, BS or any one of hundreds of mods I've downloaded.
Someone suggested Surface Tension, but I just played trough that and it's not.
Anybody got any ideas?
Hmmm ... thats sounds like Sven Co-op maybe?
Was it multiplayer???
If anybody is interested the map is asmap11b from Azure Sheep.
A big thank you to all who tried to help. I can now sleep properly.
... after a whole week of no sleep??? :lol:
