Sorry internet! There were a few issues with the current version. I've uploaded a new version for the full copy. Here are the fixes:

1) Fixed level 1 going to the next level, Benalla. If you have the full version, and could not continue after you searched the body of the Commander near the train, and don't want the new version, the code for the next level is 136. Click on the 'Continue' button on the main menu and punch in that code to access the next level. 

2) Gun icons now have a small image of the ammo type they use.

3) Tutorial level has a section about the gun types and the ammo.

If you see any other glitches, please let us know! Thanks!
