~ RESEARCH LAB ~

Your Quake II walkthrough for the Research Lab: close the hangar, destroy the black hole generator, and steal the commander's head. Get the Blue Key and navigate the facility.

Alright, we're heading into the Research Lab in Quake II. This one's got a couple of key objectives: you need to seal off the main hangar bay and take out a nasty black hole generator. Plus, there's a secondary mission to find the Repair Facility and snag the commander's head. Let's get this done.

You'll start off facing a locked door. Look to your right, there's a console there. Use it to unlock the door, then head on through. Follow the corridor, and you'll hit an elevator shaft that's blocked by a force field. Keep going straight past that for now, you'll see two doors to your left and right.

Head into the testing area on the left. Be ready, some Iron Maidens are gonna pop right out of the floor. Take 'em down, then go through the door in this room. Follow the next corridor, and you'll find another door. Inside here, you'll run into some Brains. After you've dealt with them, look for a computer console. Use it, and a Blue Key will appear right next to you. Grab it.

Now, backtrack through the two doors you just came from, then go through the one directly ahead of you. Follow this corridor until you reach a door that needs that Blue Key you just picked up. Open it and go through. You'll find yourself at an elevator; step in and ride it down.

Once you're at the bottom, follow the new corridor. You'll be dealing with Parasites, so keep your weapon ready. You'll spot the Repair Facility to your right, but don't go in just yet. The elevator leading into it is blocked by a force field. Instead, go left and you'll find another computer console. Use it to lower a maintenance bridge.

Head over to the left of the Repair Facility and cross that maintenance bridge. While you're on the bridge, you'll see two buttons on the left side. Here's the tricky part: you need to get a running start and jump to hit those buttons. Pressing them will disable the force field blocking the Repair Facility entrance. Warning: You absolutely have to run to make this jump; walking won't cut it, and you'll fall. Once you've hit the buttons, go through the Repair Facility door and hop on the elevator to ride it up.

At the top, grab the commander's head sitting on the left. Now, you need to make your way back to that console that requires the head. Go through the door that was previously blocked by the force field. Then, head through the door on the left to move on to the next level. Good job getting that head!
