How to Play Thunder Cross II (Japan)

Thunder Cross II (Japan) — About this game

Thunder Cross II (Japan) lets a modest ship grow into a formation surrounded by as many as four options. Special enemies release the items needed to build that support, change weapons and improve speed. The formation itself is adjustable, giving the options a different distance from the main ship rather than fixing them permanently alongside it. Follow the horizontal battlefield while deciding whether a tighter arrangement or a wider spread better suits the enemies ahead, and collect upgrades without flying blindly into the next attack.
