This is the demo level, controls will pop up as you go. If you forget, you can press esc (on pc) to pause and view all the controls. You can also restart the level from this screen.

When you first load the game, you'll be outside a cool-looking ship. Just run the the right, talk to the hologram for story and context, and then continue running to the right. You'll be teleported to the beginning of the level.

Now run to the right and press E while standing near the green button module to unlock the door. From here, you will want to jump up onto the platform, and then double jump to the left. You'll have to crouch in some parts, using S, but it's pretty straight forward. Press E while on the blue warp to teleport up. To your right will be a stalker that will walk towards you and will hurt you if you let it get too close (obviously). It takes three bullets or three kicks to kill. Run to the right, jump straight ahead, press the green button, and back track.

Now run to the left of the previous moving platform and drop down. There will be another stalker waiting for you. Next, it's best to kill the red spike blob thing. Crouch first, then shoot it twice to kill it. It won't move at all, but it does pretty heavy damage if you run into it. Then you'll need to press the green button, dropping a block down onto the platform to the left. pressing the green button again will reset the block. push it into the green acid gently, and jump onto the block. Ideally, it should be almost right under the low ceiling thingy. Now, carefully jump onto the ground to the right. (Both of these jumps are double jumps, and very hard ones too. Personally, this part was frustratingly hard). Kill the stalker, and run to the end of the hallway to get the keycard. Backtrack again.

Back to the same moving platform from the beginning. Keep it all the way to the left. The goal is to get to the high ground on the right. To do this, you'll have to jump from the platform to the area on the left, and THEN to the area on the right. It was a VERY hard jump for me, it took ages. Once you get there, hold down the yellow button to move the platform all the way to the right, and then jump up and use your keycard to unlock a door.

Here's a part where I got stuck personally -- you have to jump down and crawl through the small section that glows orange and looks like crates/cages to the right of the bottom yellow button.jump up and go through the now unlocked door. You get a 16 more bullets. After the hallway, there will be another stalker and another tough jump. I recommend killing the stalker first, then jumping from the box to the high platform on the right to press the green button and unlock the door.

This marks about the halfway point, and also where things get more intense. We continue.

Running though the hallway to the right, there's another stalker to kill. This section is much more complicated, and there's more flexibility in how you do things. In my mind, you can go one of two ways, depending on if you need to heal or not. Trust me, if you're low on health, you're gonna need the heal. Either way, you can ignore the researcher (the woman on the ground) for now.

IF YOU NEED TO HEAL:
Jump up onto the middle platform, and jump up to the left. There's a stalker; It's an awkward place to kill with really close quarters, so be careful. The tentacle looking thing up on the high platform is a healing station, but you can only use it once before it tires out. This is why I recommend you choose when to heal carefully. Enjoy the short cutscene.

Once you've healed up, fall back down to the middle platform. Run past the researcher, and past the first warp. Crouch to get through the hallway to the right, and use the warp there. Warning, there will be a stalker on you left and right. I tend to kill the one on the right first, as its closer, and then run to the right to put some space in between me and the stalker. After killing both of them, press the green bottom to your right, then turn around and continue to your left. There will be one stalker and one floaty tentacle thing. Kill the stalker first, and make sure you have bullets for the floaty little ♥♥♥♥. it shoots out pink balls, which you can dodge by crouching. The best way to go about it in my experience is to shoot in between pink balls and crouch to dodge. Four shots will kill it.


IF YOU CAN WAIT TO HEAL:
Jump onto to the middle platform. Run past the researcher, and past the first warp. Crouch to get through the hallway to the right, and use the warp there. Warning, there will be a stalker on you left and right. I tend to kill the one on the right first, as its closer, and then run to the right to put some space in between me and the stalker. After killing both of them, press the green bottom to your right, then turn around and continue to your left. There will be one stalker and one floaty tentacle thing. Kill the stalker first, and make sure you have bullets for the floaty little ♥♥♥♥. it shoots out pink balls, which you can dodge by crouching. The best way to go about it in my experience is to shoot in between pink balls and crouch to dodge. Four shots will kill it. Now It's DEFINITELY time to heal, lol.

Use either warp to get back, and jump onto the middle platform, and then jump up to the left. There's a stalker; It's an awkward place to kill with really close quarters, so be careful. The tentacle looking thing up on the high platform is a healing station, but you can only use it once before it tires out. This is why I recommend you choose when to heal carefully. Enjoy the short cutscene.


Now that you've successfully managed to survive that wave of monsters, it's time to actually start saving someone. Jump up to the researcher and pick her up with Q. Jump down to the warp, and run all the way to the left. before you jump down at all drop her with Q again, as you can't jump while carrying her. Across from the green button near the acid (the one that resets the box), there's a arrow and questions mark drawn on the wall that marks a secret passageway. This is another part where I got so so SO stuck. Anyway, crouch and go to the right through the invisible passage and get the datacore. Continue to the right and you'll drop down. Go to the left and open the door. Jump back up and carry the researcher down and through the door you just opened. It's best to drop her for a second here, monsters are ahead. First is a spike blob, then a stalker. You can kill the stalker first by shooting over the spike blob, the crouch and kill the spike blob. You can also kill the spike blob by kicking it, if you're out of bullets. You can kill most anything melee, it's just harder to do for me personally.

Run to the left more, and you're at the extraction zone! Congratulations, ya made it past the first stage.

If you need a visual, here's this slightly confusing walkthrough video (no commentary) I found on youtube:

Run forward and grab your ammo, don’t forget to reload!

First thing I tend to do is drop down through the first drop and crouch; the second way down you have to deal with an (avoidable) stalker. All the way down is one of those fast-as-♥♥♥♥ things, you have to crouch to shoot them. I didn’t kill it on my first try. The door is locked on the other end of the hallway, so use the warp.

To your left is the extraction zone, to your right is parkour to a stalker and a button. Your best bet is to jump up there as fast as possible to kill it instead of waiting for it to drop down, as i sometimes do. If you have enough time, this is a great place to save ammo by using melee.

The button will drop a box down. First thing I do is do the parkour right above it and grab the data core. Next, push it over to jump up and unlock the door.
