"Start with two gas grenades that impair movement, blur vision and cause damage over time."

- Description of Nova Gas in Create a Class 2.0

Nova Gas is a Tactical Grenade that is featured in ''Call of Duty: Black Ops. ''

Overview
The Nova Gas acts similarly to Tabun Gas or Stun Grenade, albeit with a damaging effect. Players receive thirteen damage per second spent in the gas, and it takes eight "Hits" with the gas for a player with 100% health to die. The gas does however dissipate very quickly so players inside the gas almost never die unless they are already wounded, trapped, or both.

Players with Tactical Mask equipped will not be affected by Nova Gas.

Trivia

 * "Nova Gas" is also the name of a chain of fuel stations in Modern Warfare 2, as seen on the multiplayer map Salvage, Overgrown, Derail and Sub Base. It was also seen in the level Wolverines!
 * The pre-release description of the grenade states that the player would begin with two gas grenades; the retail version only allows one, and the description was changed to match. This was probably added to stop the from being "spammed". However, equipping Warlord Pro still gives the player two cans of Nova Gas.
 * The effects of Nova Gas do stack. Multiple cans of Nova Gas laying in the same area produce two times the damage of one.
 * Despite the similar name, Nova Gas is not nearly as lethal as Nova 6, which kills immediately after inhaled, but both gases bear a similar appearance. It is likely that Nova 6 was formed into a tactical grenade by scientists, intentionally removing it's potent lethality, although it can kill, it most often does not.
 * The grenade has the same effect as the Tabun Gas grenade from WaW, except it adds the damage effect
 * Completing the Nova Gas challenge in order to unlock Tactical Mask Pro can be more difficult than the challenges involving the other Tactical Grenades. One reason is because a user only has one Nova Gas grenade per spawn (unless Warlord Pro is in effect), versus two Concussion or Flashbang Grenades. Another reason is that the Nova Gas has a very small radius, and the gas quickly dissipates. Finally, Tactical Mask immediately protects users against Nova Gas, making it much more common for the Nova Gas to have no effect on an enemy versus the other grenades which are only blocked by the Pro version of Tactical Mask. A way to get Nova Gas kills easily is to throw it directly at an unsuspecting enemy and quickly kill him.
 * A thrown Nova canister says "Tabun Gas" on the side. It is most likely a re-textured Tabun Gas from Call of Duty World at War.
