Just... amazing. Wow. Whew. Kinda can't describe it. =P
Very good. =)
Meh, it's alright. Could of done with a lot of polishing and better enemies.
Absolutely perfect in every way. =D
Amazing. That is all.
Brilliant. As good as a mod can get. Occasionally some things felt underealised but honestly, it doesn't get much better than this. Only way you could've made it better was probably with Valve's help. Amazing.
Awesome game, really good use of the Source engine by a very talented team. Only problem is that a certain companion just so happens to be a massive tool as well as having a fail AI. And occasionally level layout makes it extremely hard to figure out where to go.
Other than that, this game is made of win. =)
The start was amazing, I really really enjoyed it and the cart ride thingo was the most fun I'd got out of Source for a while. However, the boss fights were tedious, the vehicle section was glitchy (I wasted about half an hour thanks to one particular bug) and the Strider fight was just plain frustrating.
A good game from an amazing team that I (mostly) thouroughly enjoyed, it's just a shame the end let it down.
