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.

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.

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.
