Armed Generator Doom Machine is a nice vertical shooter where you battle only one boss at a time. Destroy him gradually piece by piece or try to focus only on the core in order to get rid of him a bit faster. There are also a few things to collect like boss shaking rockets, greater firepower and a speed up item.
Info:
The game features also online scores, a boss editor and a 2 player co-op mode.
