The dessert's a bad place for anyone. We'er being kept captive in the north and our major fire power is kept under a force field in the south. The land is seperated by a stone wall and all hell breaks out everywhere.
Simply go and invade a small building. No keys required. One force field. Ammo and weapons are a little tight. a lot more ''medium'' enemies in close quarters. It's a bit harder than the above one, but it's still fun.
This is a awesome meteor mod with a few hours of gameplay. Although this mod starts with easy levels and draws you in it will supprise you with some rather challenging battles. It even includes a maze of death to keep you puzzled for ages.
