Now updated to include continues for all difficulty levels, Recycl-o-Ray mapped to L/R buttons (L1 and R1 buttons on the PSP), autofire modes and smaller collision box, making for an even 'Acer' shmup than before!

Help legendary star fighter pilot Ace Armstrong defeat the Scumbag invasion of earth in this modern take on classic old-school shoot-em-ups, with an added 50s Sci-Fi twist and plenty of Scumbag-bursting humour.

Fly Ace through several action-packed levels, each featuring a huge boss with unique attack patterns to defeat!

Use Ace’s mighty Recycl-o-Ray to suck up the essence of defeated Scumbags and use their own weapons against them. Can you turn back the Scumbags' tentacled tide of terror?!
