Algodoo

Y12 45.ACP SMG.

To shoot:
1. Pull the mag in. (weapon is allready cocked and it fires from open bolt)
2. Set the firemode ("S" for safe, and "A" for auto)
3. Pull the trigger.
4. If the mag is empty, remove it just by pulling it out.

Weapon has integrated 20mm grenade launcher: (to fire grenade launcher)
5. Open the GL and slide the grenade in. (GL opens downwards, IT DOESN'T SLIDE like the M203 does)
6. Set the firemode on "GL".
7. Pull the trigger.
8. Open the GL for reload.

ALWAYS SET THE LEVER DIRECTLY ON THE CHOOSEN FIRE MODE! Do never leave the lever half of the way between firemodes.
This one was pretty fun to do, it jamms sometimes, but I think its obvious.
Have Phun.

[UPDATE]: Solved the problem with the firemodes selection while bolt is closed.
