Reaper

"Reapers, move in! Slaughter 'em boys!"

- Reaper commander

The Terran Reaper is a Terran infantry unit introduced in StarCraft II.

Reapers are the most hardened Terran criminals. Potential Marines who prove too intractable even after neural resocialization are instead sent to the "Icehouse" in the Torus system, where Reapers are trained.

Reaper troopers are chemically altered to make them even more aggressive before being subjected to brutal training in close-quarters combat and the use of their jet packs. A Reaper who survives two years of duty is granted a full pardon and freed, his debt to society fully paid. In five years of service, the Reaper Corps has yet to have a single trooper survive more than six months.

Game Unit
Reapers are armored in a fully self-contained body suit, equipped with a jetpack for horizontal and vertical maneuvering. This enables the Reaper to travel up and down ledges, making it ideal for scouting and hit-and-run attacks.

The Reaper is armed with dual P-45 Scythe Gauss Pistols, which are small enough to ignore the specially hardened shield of the Protoss Immortal.

Reapers were produced from the Merc Haven at BlizzCon, using a different technique than other Terran infantry units. The Haven can house up to four Reapers, and the entire supply can be bought all at once; eventually, the supply will recover. Reapers had a very quick build time. However, according to Blizzard Entertainment they are now built from the Barracks.

Despite their jetpacks, a Reaper can enter a Bunker.

Mines
Reapers can throw a mine (D-8 explosive charge) onto the ground, which takes several seconds to detonate. During this time, the mine can be destroyed. There is a red timer bar that shows how long until it will detonate.

The mines do not distinguish between allied and enemy forces, and will even injure Reapers that stand too close to the explosion.

The mines inflict significant damage to buildings.

Stimpacks
Reapers are fond of stimpacks and can presumably be upgraded with them. They did not possess this ability at the BlizzCon demo, however.
