Battery weapon

Go the map where you select the room you are to play next. Somewhere along the line you will be allowed access to the tree outside the level, to race as a snail. Finish in the top three to receive a battery as a secondary weapon. It has infinite shots and is very strong, but only seems to work on the Boss levels.

Restore life meter

Enter the bathroom in the parent's bedroom in the convoy mission. Shoot the bathtub faucet to turn on the water. Fly through the stream of water to refill your life meter. This also works with water sources in other levels.

Control lighting

Shoot or touch the light switch on the wall with the airplane or helicopter to shut off the lights.
