Call of Duty: Black Ops is a 2010
first-person shooter game developed by
Treyarch and published by
Activision. It was released worldwide in November 2010. Black Ops is a first-person shooter, retaining the same gameplay mechanics as previous Call of Duty titles. The player assumes the role of a foot soldier who can wield various fire/arms (only two of which can be carried at once), throw gre nades and other expl0sives, and use other equipment as weap0ns. A player close enough to an enemy can kill with one knife blow. A character can take three stances: standing, crouching, or prone. Each affects the rate of movement, accuracy, and stealth. The player can drop to the prone stance from the standing stance while running (colloquially known as "dolphin diving"), and can momentarily sprint before having to stop. The screen glows red to indicate damage to a player's health, which regenerates over time. When the character is within the blast radius of a live gre nade, an on-screen marker indicates where it is in relation to the player, helping the player to move away or to throw it back. Among the weap0ns new to the series in Black Ops are crossbows with bolts and expl0sive ammuniti0n, Dragon's Breath rounds and ballistic knives.
