Walkthrough

1
After dealing with the initial Antaresian Juveniles and Major Mechs, grab cannonballs and proceed to the next supply depot.
2
Use the minigun on Juveniles, then switch to the cannon for Major Mechs and Bulls. If cannonballs run out, use the Devastator and retreat.
3
At the next supply depot, find jumbo health and armor. Shoot the wooden crate to reveal the final secret (4/4) containing Devastator shells, unlocking the 'Top Secret' achievement if all secrets are found.
4
In the next area, use the minigun on Kleers and the cannon on Khnums. Expend your arsenal to survive the massive horde.
5
Continue through the canyon, collecting Devastator shells, cannonballs, and jumbo health.
6
Face the final attack: a massive horde of Bulls and Kleers. Use all available weapons and tactics, including running away, to survive.
7
Kill the last Khnum and enter the final area. You'll receive the 'The Doorman Should Wear A Suit' achievement.
8
Prepare for the final boss, Ugh-Zan. Run to the building on the right for jumbo health and cannonballs, then to the other building for more health, armor, and the JETPACK.
9
Equip the JETPACK and fly. Do not attack Ugh-Zan directly as he regenerates health quickly.
10
Fly to glowing red spots to pick up metal rods. Your goal is to throw these into Ugh-Zan's back.
11
The best opportunity to throw rods is when a Sandwhale grapples him.
12
After embedding a few rods, Ugh-Zan will be zapped by lightning, temporarily disabling his regeneration. Use this window to kill him with your cannon.
13
Enjoy your victory!

Tips

Don't be afraid to use cannonballs on Major Mechs early on.
The minigun is effective against Antaresian Juveniles.
When facing Major Mechs and Bulls, the cannon is your best bet.
Retreat and use the Devastator when you run out of cannonballs.
The final secret is hidden beneath a wooden crate containing shotgun shells.
Use everything in your arsenal against the Kleers and Khnums in the party time area.
The final horde of Bulls and Kleers requires all your resources and evasive maneuvers.
For the Ugh-Zan fight, prioritize collecting metal rods and throwing them into his back rather than direct damage.
Exploit the brief period of disabled regeneration after Ugh-Zan is zapped by lightning to finish him off with the cannon.

Upon completing the game on Serious difficulty, the 'Mental' difficulty will be unlocked. The final boss fight awards the 'The Doorman Should Wear A Suit' achievement.
