Okay.

Step 1: Load up onslaught mission and jump into the back room (walljumping)

Step 2:Wait for the zombies to pile up on the front door and kill them all at once with grenades. Also use rocket launchers to clear up zombies.

Step 3: When 1:00 comes, the back doors open, and you rush out and kill the boss.

Kill dark minions that come in.

This way has a high chance of killing you but will also get you 4,000-6,000 XP per round.
