Three guns in the pillar of autumn
Towards the beginning of the game, there is a way to
bypass the two weapon limit and carry three weapons at once. On the
first level, make your way to the bridge. After speaking with the
captain, quickly run out of the bridge before the chapter name
disappears. If you were fast enough, the checkpoint at the door will not
trigger. Now run to the mess hall and get your Assault Rifle and another
weapon. Now, run back to the bridge and trigger the checkpoint. When you
go back towards the mess hall, the pistol will appear in your hands, and
you will be carrying three weapons instead of two. Each gun reloads and
exchanges normally. Note: This only lasts for the first level.
