More guns at final Boss
If you have a jet pack, fly up and destroy the beer blimp. Guns and health will scatter on the ground, allowing the final Boss to be killed easier. Note: One of the best weapons to use against it is the Devastater.

Shrapnel City: Tier Drops
There is a tenth level on Shrapnel City called Tier Drops. To get there, go to the movie level and go to the stage with the NASA sign and the body parts with a telescope. Kill the alien with the chain gun and press [Use] on the sign. A door should appear with the caution sign that ends the level. Do not go to the stage with the ship, or this will not work.

Shrapnel City: Secret level
Go to the Hotel Hell level and go to the fountain by the pool. Step through the waterfall, then go behind a bush. You will see a radioactive waste sign like the ones that mark the end of a level, except it is gray. It will take you to the secret Freeway level.
