Seeing that the grenades can kill multiples enemies at the same time i think it will be useless...a bit like Neo vs Smith's clones...no matter how many there are, he repels them outside a predetermined radius :roll:
Although it would be fun to have a suicidal granger, i think it will imply that most of the time, the grenade wouldn t be able to damage more than one alien (for example one goon got hit, and block most of the damage for the others aliens) so the grenade would become quite useless.
This is only a wild guess...I didn t study Q3 engine.
