Upon exiting the ship, defeat 4 FLAME BLARG and ROBOT SPINNERS. Take out 3 BLARG GRENADE THROWERS across the ramps, then 2 more to the top left before CRANKING THE BOLT to create a bridge.

After the bridge forms, defeat 5 ROBOT SPINNERS. Enter the WEAPON TEST AREA and defeat 3 sets of 4 FLAMETHROWER BOTS.

Head up the LIFT, grabbing the RARITANIUM to the right before ascending. Once at the top, defeat 3 BLARG TROOPERS and 8 JETPACK BLARGS.

Proceed down the middle to find a HOLOCARD PACK. Head right, jump across to face ROBOT SPINNERS and 2 WARBOTS.

Enter the next WEAPON TEST AREA and defeat 3 sets of GRENADE BOTS.

Exit to face 1 WARBOT and 2 BLARG HELICOPTERS. SWINGSHOT across to defeat 3 BLARG GRENADE THROWERS.

(Optional Restock) Before the next SWINGSHOT, restock if needed. Fake the SWINGSHOT and head back to lure out ROBOT SPINNERS. Use the PLASMA STRIKER to defeat JETPACK BLARG.

SWINGSHOT across and destroy remaining ROBOT SPINNERS and the ROBOT GENERATOR BOT. Head up the LIFT.

Jump backwards to the left to find the GOLD BOLT. Ride the rail. Upon landing, face 2 JETPACK BLARG, ROBOT SPINNERS, and a ROBOT GENERATOR BOT.

Enter the next WEAPONS TEST AREA; SHEEP will be dropped instead of bots. Prepare for a difficult battle.

Use the PLASMA STRIKER from the WEAPONS TEST AREA to take out enemies before running out of ammo. A DROPSHIP will release 2 BLARG TROOPERS, followed by 1 WARBOT, 2 BLARG GRENADE THROWERS, and 2 JETPACK BLARG.

At the very end, another DROPSHIP will appear with 2 BLARG HELICOPTERS. The final WEAPONS TEST AREA contains many FLAMETHROWER BOTS (a good spot for weapon training).

Head into the HQ, talk to the GUY, and use the HYDRODISPLACER to proceed to the race.
