Strategy

It's best to either to run a path to every zone on the map or to guard 2 or 3 zones at a time, whatever goes for you. The best weapon to use is the Rocket Launcher, you can find some in the center building. Also, it's better to avoid the SentryBots than attack them since they're so hard to kill, unless you have a Rocket Launcher.
