Auto Axe (The Pitt)

The AutoAxe is a melee weapon that will be added to Fallout 3 with the release of The Pitt downloadable content pack in March 2009.

It is expected that the Axe will be able to inflict large amount of damage with its sharp rotating blades. However, due to its apparent size and weight, it will probably be somewhat slow, assuming it's wielded in an actual axe-like fashion and not used as a chainsaw or Ripper. The damage that is done by this weapon can be increased with the Auto Axpert perk which will also be available with The Pitt.

The Autoaxe being used by an NPC in the Gametrailers teaser for The Pitt appears to work much like a Ripper

Concept
The AutoAxe is a concrete saw supposedly made of old car parts. Its basic design is very similar to modern rotary-bladed concrete saws, and the safety yellow color indicates it is intended to be used as an industrial tool. It is not surprising that such a tool would be found in an industrial area, such as The Pitt. However, the AutoAxe could also be interpreted as a large angle grinder. It also may have been used to clear debris before the Great War.
