Uzu Keobukseon

Uzu Keobukseon ia a Korean shoot em up translated as Space Turtle Ship and it isn't actually that bad and is certainly better than some of the taito and teoplan ports of some games. The music is a little weak but the game is fun with armour and actual weapon upgrades. You always have 2 weapons but they are both upgraded to something new each time you collect enough power ups and you boat/ship also upgrades its armour. taking a hit reduced your power up level.
