Algodoo

An old german single use anti tank weapon, the Panzerfaust 60m. Intended for defeating armor, it fires a 150mm shaped charge warhead.

This one only fires an HE warhead though, but other than that it's very close to the Panzerfaust in performance, with a muzzle velocity of 45m/s and a leaf sight graded up to 60m in 10m intervals. Sight consists of 6 lasers colored from red to green, green being the 10m sight and red the 60m sight.
The sight is flipped up by dragging it.
The trigger can be pulled either manually (pull the frontmost lever done) or by pushing Enter.

Runs at standard frequency. Does not work with Phun.

Edit: i don't know if this is how the trigger is supposed to work, I just did it the easy way.
