Sturm

The red reactor on its back (×2.0). Arms, torso and legs take only ×0.6. Bullets on the propeller do nothing. Explosives ×2.0 anywhere.

An armless Soldat with an aircraft engine and three blades in place of a torso. Chase 1 (B1 Maintenance Passage): contact kills; run to the red light, first right, up the stairs, crouch under the beam and take the chute on the right. Chase 2: B3 Maintenance Passage, north side.

Before the fight: using Heisenberg's Key on the B1 door locks you in with it. Finish everything else in the factory first. In the Power Room: the "Sturm" file (#39), First Aid Med, Handgun Ammo ×25 and a Mine. In the maze: Handgun Ammo ×30, a Mine and Sniper Rifle Ammo ×10.

Moves: a straight-line charge (it revs first and can't turn); after enough damage it overheats and bursts into flames: a flamethrower (the fire lingers on the floor), three charges in a row and rampages in every direction.

Complex Mechanical Heart (45,000 Lei). Afterwards, File #40 and the Cigar (3,000) in the Cargo Control Room.

15,000 HP. Rough estimate at Standard's starting rank: about 5 un-upgraded M1851 Wolfsbane shots to the reactor. Game8's weapons: V61 Custom and SYG-12 (the shotgun uses less ammo). Save your explosives for Mutated Heisenberg.

• Village of Shadows: it barely shows its back: shoot the propeller or the legs, which still damage it. Listen for the fire wind-up and dodge at all costs. In the first chase 2 Haulers block the way: kill or stun them and keep running. One source says 8 shots from a fully Power-upgraded magnum do it (unconfirmed).
• Knives Out: let it hit a wall, crouch behind it and knife the orange dot.
