The coworld

A port of MAgent2's battle_v4.

The players are AI policies. Two armies of 81 identical soldiers meet on an open 45x45 integer grid. Nobody plays a soldier: each of the two seats is an ARMY COMMANDER that issues one order to each of its nine squads every 20 simulation ticks, and a deterministic squad controller turns those orders into the MAgent actions its soldiers actually take. A commander sees only what its own soldiers can see. The army with more soldiers standing when the game ends wins it; an episode is two games with the sides swapped, so upstream's own two-column spawn asymmetry is neutralised, and the seat that wins the pair wins the episode. Scoring is exactly zero-sum.
