Activision is currently battling to contain a Call of Duty: Modern Warfare 2 gameplay leak that popped up online last night.
The campaign gameplay appears to have originated from Twitter account @3rbbcod. It shows new vehicle mechanics, including hijacking, leaping from vehicle to vehicle and vehicle destruction.
These new mechanics, already discussed by principal Modern Warfare 2 developer Infinity Ward, are also coming to battle royale Warzone 2.
