Starcraft – How to complete the “Outmatched: 4 Very Hard AI” achievement

achievementsstarcraft-2

I am trying to complete the "Outmatched: 4 Very Hard AI" achievement:
Win a 1 vs 4 Multiplayer Custom Game with no Allies against 4 Very Hard A.I. opponents.

Any tips are welcome.

Thanks.

P.S. I would probably better to start from easier achievements, but it should be feasible to complete the hardest one too.

One approach - which could probably be deemed cheating - is to play on the map Burning Tide. The goal of this map is to be the first team to collect 15,000 minerals.

You can get all the Outmatched achievements this way, because the AI players spend minerals on units and buildings, yet they do not attack. The AI players also do not collect the minerals deposited by the lava - this becomes important when going against 3 or 4 AI opponents.
