Game Boy Wars — About this game
Game Boy Wars makes factories, roads and the space around a unit part of the same plan. Build forces with income from captured facilities, move on the staggered battlefield and choose a target the unit can actually hurt. Infantry can turn a quiet flank into a threat to the enemy headquarters, while an expensive vehicle still needs support. Win by taking the capital or clearing the opposing force, rather than measuring progress only by damage dealt.
