Infiltration

You'll start by needing to crawl under a wall. After that, jump up a couple of ledges to reach a red door. Hop onto another ledge above you and head to the right. Work your way down the ledges until you see a door on your left – go through it.

Once inside, you'll need to shoot through a cracked floor. Drop down and immediately crawl to the right through a tunnel. Be quick, because a space pirate is about to sound the alarm!

Keep running to the right and shoot diagonally at the cracked ground as you fall through it. You'll need to do this again as you run left and then right. After that, run off the next ledge and hold the direction left to grab onto the ledge below. Climb up, then run right, crawl under a wall, and go through the door you find.

Run towards the wall as you fall through the floor. Wait for the gate to open, then proceed through the door.

This next room has searchlights. You absolutely need to avoid them, as they will sound the alarms. Climb to the top of the shaft and go through the door you find there.

Head to the right and shoot the 2x2 block directly above you. Climb up, then shoot a cracked section on your left. Climb up even further and go through the door nearby.

You'll need to shoot through some walls here. Keep going until you enter the save room just ahead. Once you've saved, go left to the next room.
