Part 52

Master Part 52 of Half-Life! Learn to navigate the treacherous reactor core, use the circular ring and buttons, and survive the alien controllers before teleporting to Xen.

Alright, so we're diving into Part 52. It's a bit of a doozy with some tricky platforming and a crucial defense sequence. Don't worry, we'll take it step-by-step. First up, you'll materialize in a room in section c3a2b. Grab that HEV station charge and gauss gun ammo, but don't linger. As soon as you appear, whip out your assault rifle and make a dash for the opposite wall with the big window. Crouch down right next to it. This is key to avoiding the first vortigaunt that teleports in on the other side – it won't be able to zap you. Now, quickly turn to face the room's door. Another vort will pop up near there; take it out ASAP.

Listen for the sound of the first vort being taken out by electrical discharges. Once you hear that, it's safe to grab the HEV charge and gauss ammo. Use the exit portal to head back to the starting teleporter area. We're going to get serious about this next part. Follow the scientist's bloody clues on the floor and go through portals 2, 4, and 7 to reach the fancy core area in section c3a2f.

LEVEL C REACTOR CORE (Section c3a2f)

You'll start on a ledge overlooking the reactor mechanism. Take a moment to study it: there are two sets of rotating platforms and a big circular ring that moves up and down between them. This ring is your main way around, but be careful – it can get crushed against the ceiling beams. Your goal is to use this ring to reach ledges with buttons.

First, quicksave! Then, wait for the circular ring to descend to its lowest point. Take a running jump from your ledge onto the ring as it's moving down. Once you land, immediately turn left and run along the ring. You're looking for a ledge on your left with a button labeled "01." When the ring rises up to meet the ledge, take another running jump to reach it. Press the "01" button.

Quicksave again. Repeat the process: jump onto the ring as it's descending. Turn left, run along it, and look for the next button ledge, this one marked "02." Jump to it when you can and press the button. Doing this opens up the two "doors" leading into the central core.

After another quicksave, jump back to the ring, then hop onto one of the moving platforms heading towards the central core. When a platform is next to one of the opened core "doors," move onto the door's ledge. Crouch-jump through the opening and into the portal. This will send you back to section c3a2c.

DONE WITH THE CORE (Section c3a2c)

You've made it past the core areas! Save your game in celebration. Whatever you do, *don't* go through the nearby exit portal – it just sends you back to the start. Instead, head through a couple of doors into section c3a2d.

TELEPORTING TO THE ALIEN DIMENSION (Section c3a2d)

Past the second door, find the red wheel on the overhead pipe. You might need to get underneath it and jump just as you press the "Use item" key. Wait for the steam to clear out three headcrabs down the hall, then turn the wheel off so you can proceed. In the dark area just past where the headcrabs were, you'll find an armor battery. (The source mentions two, so keep an eye out!).

Nearby, there's a side alcove with a ladder. Climb up and go down the corridor. A scientist will open a door for you. After he does, check around for tons of supplies while he chats. He'll eventually open a case with the long jump module. Grab it and equip it. To use it, run forward, crouch, and jump immediately.

When the scientist opens the next door, get him and the security guard to follow you through the noisy scanner. Use any available first aid or HEV stations, then head into the big teleporter chamber. Leave the scientist and guard near the chamber's entrance. Save your game here – this is important.

Soon, alien controllers will start teleporting in. You absolutely *must* prevent them from attacking the scientist who's opening the gate. His protective glass won't hold forever, and if he dies before you can teleport out, it's game over. You don't need to kill every controller; your main job is to distract them so they attack you instead.

There are a couple of ways to do this. One is to use the high ledge you can reach via a red ladder on the wall. Run around the chamber to find it. The downside here is limited space to dodge, meaning you'll take a lot of damage. Plus, you'll have to drop off when it's time to teleport, taking more hits.

A potentially better strategy is to stand on the floor on the opposite side of the chamber from the scientist, near the narrow ledge leading to the teleporter core. You'll be less visible here, but most controllers should still target you. Watch out for any that teleport near the high ledge and quickly shoot them to draw their attention. Note: Avoid using the gauss or gluon guns here; save that ammo for later. When the scientist tells you to get into position, quicksave. Then, get to that spot on the floor opposite the scientist. Keep distracting the controllers until the scientist says it's time to go. Immediately run along the narrow ledge to the portal and jump in. If you're quick enough, you'll be teleported to Xen.
