Gain Ground — About this game
Study the enemy positions before choosing a fighter. Normal shots and a character’s special weapon cover different situations, so compare reach and movement with the route ahead. A direct attack is not always the safest way to reach a trapped person or an exit. Clear enough room to move, then decide whether to continue fighting or withdraw. Plan the return path as carefully as the approach.
