Minigun

The Minigun is one of the Tier III (3) weapons listed on the shop, colored in cyan. Although it seems op, but once a company that shipped it says that just a plain, starting minigun isn't gonna be a massive boss killing machine. Its the first commando weapon obtainable in game.

Info
Because of the minigun being rotary, its capable of shooting in a very high firerate, which allows the minigun to deal 588 DPS, also with 150 ammo, which gets you to get blasting for a very long time. It's particularly effective on crowds, and bosses.

Trivia

 * Minigun was formerly the most expensive weapon in the game before being overrode by Jackhammer.
