Mine Thrower

Resident Evil 3: Nemesis
The Mine Thrower was an experimental weapon designed by Umbrella and issued to at least one U.B.C.S. operative during the Raccoon City Outbreak. The weapon works by launching small dart-shaped proximity mines which can attach to surfaces and explode upon detecting nearby enemies. These darts can also be used to attach to enemies directly, therefore operating somewhat akin to a miniature rocket launcher, albeit with a slight delay between impact and detonation. Ammunition for this weapon is very scarce, and cannot be made, and should be saved for fighting the Nemesis or large groups of zombies. The mine thrower will damage Jill if she is too close when the dart explodes.

The Mine Thrower is first found by Jill Valentine in the St. Michael Clock Tower on the body of a dead UBCS mercenary.

When upgraded with an Infinite Ammo case, the mine darts gain a powerful seeking ability that will guide it towards the heads of enemies. Additionally, upon impact with an enemy, the dart will explode instantly, then exit target, and seek the next nearest enemy. It will detonate on every single hit, often resulting in a single dart killing everything in range. The darts track their targets very effectively, but may miss if not given enough travel time to change their trajectory. They will detonate permanently upon contact with the environment.

Resident Evil 4
The Mine Thrower fires explosive mine darts that detonate after a short time (the duration is slightly reduced in the non-Gamecube versions). The darts stick to surfaces and enemies, causing them to stagger slightly before exploding, doing damage equal to a Hand Grenade. It costs 9,800 pesetas, and a scope can be attached for 8,000 pesetas. The firepower stat of the Mine Thrower actually refers to its explosive blast radius. As with the Mine Thrower in RE3, the blast from an exploding dart can damage Leon if he is too close when it detonates. The Mine Thrower takes up 10 spaces (5x2) of Leon's inventory. The scope takes up an additional 4 spaces (2x2). To start, it has a firepower of 2.0, can fire every 1.33 seconds, take 3.43 seconds to reload, and has a capacity of 5 darts. Fully upgraded, it has a firepower of 6.0, can fire every 1.33 seconds, takes 2.57 seconds to reload, and has a capacity of 10 darts. The Mine Thrower costs 192,800 pesetas to fully upgrade (200,800 including the scope). Its exclusive upgrade increases the blast radius even further and gives the mine darts heat-seeking capabilities. However, this makes head- or legshots impossible unless if it's done in close range. Mine darts are very rare and do not appear unless Leon has a Mine Thrower. Many players classify the Mine Thrower as the worst weapon in the game while others choose to believe that it is a very powerful and entertaining weapon, second only to the Rocket Launcher. �
