Not only full auto (though there will be a mode for it) but burst (multiple rounds per pull) and semi (one round per pull). The most used mode will be semi, and it'll be limited to keep me from outpacing the mechanical device (in particular the feed mechanism), a big problem when the trigger pull becomes a mouse click. A future project will attempt to improve the feed mechanism, basically by letting the hopper know what the gun is doing.
