On omaha map. I found out by mistake, that if you choose axis, go to a machinegun, hold it, then change team, you are still by the gun This means that you can get up pretty fast.
Now this is a bug, and it can be used by faul ppl to cheat. I must admit i did it couple of times, but as always, it got boring as cheating always does. Now dont go do this because cheaters ruin games! I think it will be fixed in a patch.
