Undercover OpsAuthor : ArcadeBomb - 51 241 plays
Play as a special forces soldier who has been parachuted into the jungle to wipe out the guerrillas. Be as quiet as a mouse as take your enemies out with a sharp knife. Surprise them when their backs are turned, but take care not to be seen, as the tiniest error could be fatal. Become a master of infiltration and survive to complete your mission!
