Sweet! Some minor spelling errors which would be nice if they where corrected; Mech Builder (poduction phase) Remaining capitals get neutral mech, tank and Procuction Center Attaker cannot retreat. If forced to retreat, units destroyed Reteating Attacking unit retreast to origin area Defender detroyed if no friendly or unoccupied area available 3x Poduction Centers Dots are missing here and there. Numbers are not used in all places.
Add the FAQ clarification regarding Secret Weapon, i.e. it can't be used to attack capitals.
Land Battles If each player rolls three times without a hit: cease fire. - This is not correct, it is three times in a row, i.e. attacker-no hit, defender-no hit, attacker-no hit -> cease fire However it is correct for sea battles.
Production Points = 6 with no capital. - 6 is the minimum you can get, with a capital or not. If you have no capital but 3 production centers with power you will get 9 plus the card value.
Maybe add something about how majority works when tied.
I would have put the battle section in between Combat phase and Victory point step so the flow of the aid sheet is the same as in the game.
