One

In this game your goal is to find out who you are. One of your only clues is a
bar code on your neck. At the beginning of the game, you awaken on the floor,
with a gun in place of one of your arms, no memory, and police helicopters
shooting missiles through your window. From here, it’s nonstop action as you
battle your way across the city and countryside, constantly pursued by the
police and miliary.

Each level of this action shooter delivers nonstop action with a total of 6
levels and bosses at the end of each.
