Sandstone Torch reference

It's an axe that normally hangs from the cealing cutting down intruders of for example an temple.

When divided into two the two pieces can either be used as seperate axes or as guns.
The guns are powered by air preasure turbines and dust. the dust which can be found inside the little turbines can be used for a flamethrower (which is more like a rappid flame bullet rifle) (two short barrels) or either used as bullets (long barrels) that give a little explosion on impact.
after 7 heavy loaded shots or a big barrage of little flameshots the dustcells in the turbine need to cool down, then the turbines will pop out of the rifle and after 10 seconds the turbines will be cooled. After they're cooled once however the dustcells don't have enough power for any flameshots, they'll have to be shot as bullets from the long barrel (these bullets give a little explosion on impact). when empty, the turbine can be ejected and replaced.
