Level 1. Seppuku Station

Start in Lo Wangs Dojo of Death. Defeat the two Brown Ninjas with uzis using your sword. You can recover health by hitting the dojo walls with your fists.

Exit the dojo through the window. A green van will crash into another vehicle, killing a brown ninja. To the left, find a gray truck with an uzi in the back. Pick it up and eliminate any enemies.

Locate the "Baggage Claim" sign and go down the ramp. Continue killing enemies until you reach some crates and a GOLD KEY. Pick up the GOLD KEY to enter the FarEast Railroad Station.

Engage the ninjas inside the station. To the left of your entrance, find a black window. Jump through it to find a Riot Gun on a ledge.

Return to the station and find a black vent. Enter the vent and proceed all the way down.

You will arrive in a room with black armor. Grab the armor. To the left of the train map, open a panel to find a Missile Launcher. Nearby, find a remote controller. Use it to control a vehicle and move it as far as possible towards a red dot on the left of your screen.

To exit, head to the right of the train map and find a vent on the top. Go back up to the first room of the train station.

Find another door in this room (different from your entrance). Enter to reach Koi Pond. Feed the fish (enemies) some bullets and defeat any other enemies. You can find caltrops behind a wall in the pool.

Enter the Pachinko Parlor. Check the Godzilla poster for grenade shells. Pick up the SILVER KEY at the Prize Pick-up space. You can obtain various items by playing the Pachinko machines, provided they are not destroyed.

Go to Platform 45 and use the SILVER KEY on the brown door. Enter and hit the switch to open the grey doors leading to the train platform.

Kill any enemies on the train platform. Find shotshells on top of the train and items behind posters. Head to the right track (the one without the train) and move forward.

Watch out for the turret. Destroy it with missiles. Blow up the tubes, and a train will arrive behind you.

Enter the train and turn right. Continue forward to find the end-level switch and complete the level.
