(adsbygoogle = window.adsbygoogle || []).push({}); Rounds 1-4

Use Knives ONLY. 130 points per knife kill compared to 60 points per Pistol kill. Do not buy the Gewyer or Kar. Let zombies in occasionally for a chance at the Bomb which is an extra 400 points/player.

Round 5

At the beginning, open the Right Side (when facing clock tower) and then open the next garage door. Buy the Thompson and clear debris at top of stairs. Have one guy turn on power, one guy open the next door to the teleporter on the right side, and one guy go to mainframe to activate teleporter. Chill in the back near the mystery box.

Rounds 6-7

Rack up points, and use the mystery box.

Round 8

Open up the rest of the doors and link all teleporters.

Round 9

Chill at Teleporter C in the tunnels or at the top of the metal stairs. I think the stairs have better escape routes.

Round 10-Beyond

Keep upgrading weapons/buying new weapons by leaving crawlers at the end of each round. Use Monkey Bombs/WonderWaffle when a teammate is downed or when a powerup is hard to reach.

This got me to round 25.
