Killzone: Shadow Fall - glitches and observations
17I recently played through this game and did some light glitching on it. Prognosis: not very breakable.
I'm not sure if it's a feature of the Decima engine or Guerrilla's own development style, but this game is much like Horizon: Zero Dawn - everything is so trigger-driven that things just outright refuse to work if you do things out of order. So that's a bummer.
In any case, here are the results of some tests around the game. I didn't really check for glitches on Youtube before this, so some of this stuff might be known already.

0:00 - in Chapter 3, the level finale happens at a laboratory. The prompt to open the door there can be hit early in the level by going right underneath and examining it through a wall. However... nothing happens after using the prompt. You just get stuck in the airlock.
0:38 - if you set up a Shield a correct distance away from a wall, you can use it to push the main character a little inside collision. It doesn't seem to help in breaching walls (at least by itself), but it does enable you to see through walls.
I thought it was a cool detail that these NPCs (that you're never supposed to see idle) have their own animations even before you've stepped into the room. I expected them to be in t-pose.
1:03 - a pointless event glitch in Chapter 6 section "Up and Running".
In the part when ATACs appear, if you run outside to hit a trigger but then walk backwards, you can get back inside before the doors close up behind you. This allows you to... get stuck indoors forever. The door doesn't open up again, nor can the enemies reach you indoors, so you're stuck stuck there.
1:33 - I did some skip tests in Chapter 5 using a "high jump" technique that I first saw in Pewable's old videos on Facebook.
Basically, after using C4 (by exploding or picking it up) or throwing a grenade, the main character's weapon goes back to default. This is such a high-priority action that it allows you to do light break-outs. If you break out of a jump right as it is starting, the main character does another jump in air automatically, giving you around 2 times normal jump height in the process.
This clip takes place in the section "Think You're Special?". It's easy to use the high jump to get on top of the level from on top of the nearby stairs and explore the fairly large and cool OoB area there
2:06 - I wanted to see what happens if you simply skip an objective by going around it. Well, in the case of "Think You're Special?", if you try to go around the objective markers, the level streaming doesn't work, leaving the next area unloaded.
3:09 - I did another skip attempt at "Make Him Pay". It would be a cool shortcut to jump on some collision and shortcut right to the path that leads to the elevator, skipping both navigation and a fight in the process... but the elevator prompt is inactive at the moment, and nothing happens when you try to use it.
I retraced my steps to figure out where exactly are the triggers that one would need to get the elevator working. Basically, there is one trigger on the upper floor before you drop down to the stairs. And then, there is a second trigger on the stairs that load the events of the lower area, including the fight and enemies.
Seeing how the triggers work in this game makes me doubt if any larger sequence breaks can ever be possible in it...
4:09 - the rest of the video is OoB sightseeing.
In "Think You're Special?" I wanted to backtrack to where the level started. It's possible to do from underneath the map, for instance. The metallic girders all around the level can be walked on both above and below, making this a pretty large OoB area to explore.
If you're under one of the rooms on the way while backtracking and look up, you can see through the floor, walls and the ceiling too. The level isn't drawn properly from this angle, I guess.
Well, the area that preceded "Think You're Special?" doesn't even exist any more at the moment, but I had to see it for myself.
5:00 - falling victim to graphics without collision and falling through the map. Nice visuals!
