Chaingun

The Chaingun deals very large amounts of damage due to the number of bullets it can send out, but this is offset by its wild inaccuracy. You may decrease this inaccuracy by crouching, or remove it entirely by wearing a battle suit.

While chainguns are decent against smaller aliens, where they really come in handy are larger aliens such as Dragoons and Tyrants. This, in combination with the battlesuit and the large cost of the item, make the chaingun more effective during later stages of the game.

A common tactic is to have several members of the human team buy battle suits and chainguns (sometimes called "CSuits or Chainsuits"), along with a few grenades, and storm the alien base. The noisy onslaught that happens is enough to make even the staunchest alien tremble in fear of the "Whirling Suits O' Death."
