I second that... alien level 14 is a real unfair nightmare! You can't really rely much on skill as your two alien muppets keep on getting themselves killed!
There seems to be a bug sometimes when you kill an enemy carrying the flag. The flag instead of returning to your base is transfered to a different opponent!
This game is at its best when you finish it with the tank and start again with the sports car, UNARMED. Driving as fast as you can avoiding machine guns and mines is pretty good. Not much cash in it, though. And a good oil spill that drives you against a couple of blue mines and its over!
Brilliant, we shoot each others hats, we shoot each other in the groin, we blow ourselves of our legs and then have to shoot it out somehow from the ground. Very nice and fun.
