A FAMAS G2 appears in the game simply as "Assault Rifle". It holds 30 rounds and can only be found on the level "2000 Docks".
A very deformed M16 type rifle, it's probably supposed to be an M16A2 or M16A3, however it is more similar to a M4A1 carbine because of the shorter barrel and handguards. It holds 30 rounds and is only available in "1970 Chinese".
Heckler & Koch PSG-1
A Sniper Rifle loosely based on the PSG-1 appears in the levels "1985 Chemical Plant" and "2000 Docks".
The SPAS-12 appears in the game simply as "Assault Shotgun". It is found in the missions "2005 Cyberden" and "2000 Docks". It Holds 8 shells. Even though it is set to be automatic, it's still pumped after each shot.
12 Gauge Double Barreled Shotgun
A Double Barreled Shotgun appears in game simply as "Shotgun". It appears in "1970 Chinese," "1950 Village, "1965 Mansion," and "1985 Chemical Plant".
A Blunderbuss appears in the game only available in "1935 Tomb". It only holds one shot and appears to be using regular shotgun shells, however neither the SPAS-12 or Sawed-off shotgun appear alongside with it, so it's safe to assume it's using its own ammo source.
