Seriously, how are we supposed to compete with a guy camping in a corner on Sword Base with the energy sword? I know what you're going to say, "toss grenades in there, come up the chute, avoid him, etc."
1. Tossing grenades doesn't do anything. The angle required to toss the grenades into the room isn't good enough. The grenade doesn't hit the wall with enough force to bounce at the enemy sitting in the opposite corner.
2. If I go up the chute, he'll stab me.
3. The other players aren't avoiding him and are dying trying to kill him. They're giving him all the points he needs to win! So, the only thing I can do is help a little by firing at him right after the sword carrier has killed the previous player and hope that I kill him.
Here is a Slayer game where I managed to hit 1st place:
When you look at my weapons, you'll notice I had the energy sword. I was hogging it so the other players couldn't get a cheap kill. Made the game challenging.
