i greatly enjoyed this mod. it had some awesome level design and gameplay and i thought the whole concept was fascinating and well executed, especially with how Alyx is evil instead of good; it was crazy how you could kill her!

I enjoyed the mod, but I confess that I don't get how to achieve different endings either. I TRIED shooting Breen many times, but he seems to be invincible whenever I'm in a cutscene, and I didn't see any other opportunities to attack him. That said, it's kind of jarring to throw a grenade into a large group of people, see the boom, and not have anyone be affected by it.

pretty good mod. I like how you use the actual voices of the characters and make it fit. Im not too far into the game but im stuck in this one part. Im in a small room that i got to by breaking a cinder block wall, it has a broken ladder that cant be climbed and a door that wont open. there isnt anywhere else to go

for some reason the door wouldnt open even though i was clicking it. eventually it did work. I got to the end and destroyed all the helicopters, so why the hell was i executed?

Pretty Decent from what I've seen, I liked the teleporter thing. However, I'm stuck getting out of it. I can get out of the teleporter, but trying to cross the room just puts me back in it. It's extremely frustrating. I'm sure I'm missing something obvious, which makes it even more frustrating. Any help maybe?

Great mod, many good challenges and the story was quite fun, even multiple endings. Overall great mod, didn't get boring and that's well done in a HL2 mod.
