Press X to roll out of the way of explosions! Press F to wave at hostages! Press forward to drive a car, and F to pick up the briefcase! And, I guess, if you get the time, left mouse button to shoot some people.
The actual multiplayer shooting of this multiplayer shooter is swampy in sensation, and takes a back seat to pointless, game-muddying additions. Players can use dogs to attack or 'sniff' the enemy - presumably incapacitating them with icky pooch nose goo - or pick up propane canisters and lay them strategically around the level, only to curse your planning as an opponent sprints past and kicks the the impromptu bomb back into your face. Weapons lack Battlefield's bite or Counter-Strike's imagined authenticity. It's this latter game that Tactical Intervention invites closest comparison to, and not just because it looks like a game from 2003.
Tactical Intervention is born from the mind of Counter-Strike creator Minh Le - the result of the self-named Gooseman attempting to make a game that goes further and deeper than the simple CS could at the time. His new game borrows its predecessor's terrorist-on-counter-terrorist bloodbaths, but the things CS got so right - precision, tactics, consistency - are lost.
