Syphon Filter 3

At the level there is one of the most lethal weapons, Spider (aka Scorpion Spider), which kills any enemy with 1 (less often 2) bullets. Even enemies with body armor will be taken out with the same success as from the K3G4.
You will find Spider on one of the forks, on the floor where the ship's Cook will go.
You can find another one in one of the cabins when you return back.
This weapon will carry over to the next two linked dock missions.
