Take to the plains recruiting countless cows in an effort to become the best Gaucho that has ever roamed them. Use your relentless army of cows to fight other players, but if all your cows are defeated, you lose.
Right click to move and order your cows to attack enemy cows with space. You can also use space to recruit neutral cows once they've been defeated.
Flee when the goings get tough. Even if you've got but one cow left, you can re-cow-ify your army if given enough time.
