Thought I would make a quick guide on this achievement. Once you load into the main menu, Select "Multiplayer" at the start. Then, go to "Battle". From there, select the parameters by hitting
and pick "Skirmish" mode as your favorite (so it tries to select that mode first.) Search up a game, and get at it. PvP is pretty low as of writing this, but I found a match after not long. We had some real players and AI filled, managed to win using the first Heros, Raider.
