I got obsessed with trying to take down that bloody chopper in that game Rad, I got carried away, kept on dying.
Regarding the Medic, once you unlock the M60 you'll be mowing down enemies for fun.
It happened later on the lighhouse map as well didn't it. I remember we had about 5 of us all firing rockets at the chopper as it flew around and around at the lighthouse area. It's was frigging ridiculous because I've been in a chopper on there and it's stupidly hard to avoid being shot down. But this guy just flew around us taking the piss.
I have the rocket launcher where you can guide it - but the piece of shit rocket loses interest after about 5 seconds of tracking a chopper. When you fire it across the map at a tank you can have the rocket dancing around - but in the air it gets to a certain height and then just gives up and zips off somewhere.
At least we won on that map though because they had 4 guys in the chopper cutting down the numbers we had to deal with on the ground.
