I was the one fighting frontlines and attacking everyone near the doors, thats how I got 500k damage. Didn't die because 2 of the healers were focusing on healing me only cause it was clear that I was making life very difficult for the opposing team. You can't actually do so much damage and kill so much and get announced as Immortal without the opposing team deciding to concentrate fire on you.
We only lost because we couldn't beat the other team's time. They didn't get throught the second door.
And they were healing me mostly, yes xD I love healers, they need more medals.
