Star Wars Battlefront 2 PC, actually- way back when the servers were decently stocked sometimes. The sort of awesome, but entirely insane round you can only get when there are no bots, just two teams of (at least) 16 players apiece.
So, bullets were flying *everywhere*- this was on one of those sandy, desert maps- explosions every which way. The droids- a line of them! A particularly cooperative bunch, marching on our last command post.
I change class- the time for action is now. A jet-trooper, I am able to clear large sections of the battlefield quickly- I must take back some of our territory...
Well, long story short, the droids were so busy attacking, that I managed to steal two command points, giving us the advantage. An advantage we held, damn it.
...Yeah, it was pretty easy, and really only happened because the enemy let their guard down, but I practically won the match, and... It was a long fight, OK? It felt important.
