Subz

Prototype of Subz multiplayer game

Find your enemies and sink 'em with torpedos. Watch the noise you create though, or you'll end of on their radar! Establish a lock for 3 seconds to enable your homing torpedo. You'll hear a warning if you are tracked by a homing torpedo, use a countermeasure and you may distract it! 

Ping wisely, as it will also alert others to your position!

Stay quiet for a while and you'll become almost invisible. Sneaky...
