Rift Atlas

The center-player spawn for each team (1v1 and 3v3 modes) has two garrisons just outside the base. Make sure to toss some extra units in there. Snipers and Elite Rangers are great units for a garrison!    

Minibases are located in lines and behind the starting bases, making them a fairly safe expansion option without the fear of overextending your defenses.    

Pushing out early to take the nearby Resource Node in the center of your side of the map may give you a leg up on your enemy with little chance of them coming in for a counterattack.    

The expansion bases on the Bedrock map are extremely vulnerable to artillery, due to the elevated ground on the north and south sides of the bases. This high ground can only be accessed from the outside, giving a huge advantage to enemies who decide to besiege the base. Keep some air units handy to grant line of sight or counter any artillery threats.
