Cool portal theme Interesting puzzles Creative

Pretty boring visuals, even if Portal-esque features were pretty cool for any Portal fans. Repetitive puzzles No voice acting/story The gas cans you need to weigh down the button can roll off easily. See below problem... I ended up dying in single player mode because my AI wouldn't get inside the doorway.The infected made the gas can roll off and I had to step on the button on the other side of the door in order to keep the door open so that they'd follow me, but an armored infected kept them there for ages. I decided to climb the ladder to help kill the armored infected while staying behind the door so I could open it in case they accidentally ignited the can, but a jockey grabbed me and incapacitated me. Despite Ellis being on the same side of the door I was, none of them came to my aid, even after the armored infected died. I inevitably died. That's partly my fault, but it would've helped if the AI was smart enough to figure out that they can unlock the door once I've already reached the other side so that they could help you if you're downed and they're trapped. After I restarted and completed that section, I got to the bigger puzzle. Where I died again. I couldn't find the route to the safe room even though I could see the glow of the door. I assumed you entered the twin doors and go through that way, but the doors wouldn't open for me. Ellis and Coach, somehow, melded through the wall and entered the safe room, leaving Rochelle and I to die since I accidentally startled the witch and she had a jockey on her. Since Ellis and Coach were already in the safe room, I guess their AI wouldn't let them leave to help.

- Creative - Original - Like portal - Randomized gas can placings - 'Tests' worked well with no glitches - Maze, having to look for the items

- Same puzzles repeated - Same environment repeated - No dialogue - Bot navigation - Became boring
