Critic
The game could have been well realised if more time were given to developers, or simply if they had been less ambitious.
This is a vertical 2-players-co-op shoot them up.
A sweet intro animated cinematic open the game, as the game primary aimed to be a GX4000 super production, halas the decline of the console rushed its release and many bugs are still present.
While being a vertical scrolling shooter, you can also scroll aside the screen, this is of course quite heavier for the machine..
But it makes perhaps a too heavy use of Hardwired sprites (need a lot of DATA space and time to upload into the ASIC) and also features too many scrollings (multidirectionnal actually, but the sidescrolling is really un-needed), sprites are perhaps too big too (given most of those are Hardwired sprites).
This game slows down a lot and your shoots (machine gun) are too small/unvisible/slow to be gameplaywise.
The copter sound is also quite annoying, but of course it is best to disable all sounds effects... due to the "bullet-time-perpetual-slow-motion".
Some colours/inks seems to have been be badly chosen/set too.
This game would have nedded less technical ambition and bigger Eprom cartridges too to be actually good.
