Totally agree. Many a time I've worked my way round the back of the enemy, picking off some nice easy kills

and found myself out of bounds, out of breath and no time to turn round

.
- More time needed to get back from out of bounds areas (I suppose you could disable your ablity to use your weapons while in an out of bounds area)
- I don't think the warning message is that clear, maybe a darkening of the the screen with the warning message bigger or some sort of noise might help.
