I seldom see this game talked about on PCEFX. Shame, as it is one of the most intense shooters on the system, though the difficulty is a bit low, especially with double lazers.
Plenty of people here have played Side Arms, so you'll be happy to know it has the same powerup system.
The first half of the game is pretty standard, but a well done port of Capcom's classic. The second half is an amazing though kinda short expansion featuring all new levels, graphics and music by Naxat.
