This is the 2nd match of the Team Series A series. It is fairly easy.

Briefing

A squad of SentryBots are attempting to take over the Ice Station asteroid. Team up with the Space Troopers to secure critical locations and repel the attack.

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 centre 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.
