Battlefield Vietnam

Battlefield Vietnam was a first person shooter released in 2004, developed heavily from the earlier Battlefield 1942. Unlike BF1942, which had literally no cut content, BFV has several bits of cut content.

Flaregun
There was originally a flaregun in BFV. It is fully modeled and has numerous animations and dynamic effects involved with its flares, but is soundless, and its flares act more like mini napalm bombs than actual flares, without the damaging effects.

Commando knife
A weapon originally included in the Secret Weapons of WWII expansion of BF1942, the commando knife can be found in the BFV game files. Its attack material is "throwing knife projectile", and indeed, its original iteration was a throwing knife. However, it has the animations and design of the BF1942 knives rather than the throwing knife of the same game. Its model, however, is of the same design as the U.S./ARVN knife of Battlefield Vietnam. This hints that, in fact, the commando knife was never intended to be used in Vietnam, and is simply legacy coding from 1942.
