The Dart Rifle is a single-shot bolt-action rifle that uses compressed air to fire darts that deliver a neurotoxin. It is available after completing the last weapon shop mission of Act 1 for the low price of 10 diamonds. It seems to be based off the M40 American-made Sniper rifle, normally chambered in 7,62 mm and itself a military variant of the Remington 700, used during the Vietnam war and always used today by the U.S military.
