To establish a fairly safe base, move all of your units to the south (past the wall) and build your base along the southern edge of the map.

There are only 3 ways into this area of the map, so it can easily be defended by light laser towers (defensive structures that attack enemies).

You will get attacked fairly early by a group of peewees (small enemy units) that will enter this region of the map through the middle entrance.

Getting an early laser tower up would really help defend against this initial assault.

Build 2 light laser towers at each entrance (at least) as this will keep away further assaults.

You can build lots of metal extractors (structures that gather resources) here, so do so and build up a big army of vehicles.
