Here's something you won't be playing the next 3 years

I thought they were using some costum models from other modders (with permission) and even some of Valve's models too (such as the vortigaunts' main body feature, the collars are new). I just didn't know they were going to do voice acting at all. Other mods such as Decay and that of the Dreamcast port of the game just straight ripped that from the originals, don't see a reason why they shouldn't have been able to do the same. It's probably for the better though.

It's a joke/estimation based on their developement time on the project, which seems to be taking forever.

I didn't mind the iron sight for the magnum, it's still better than its scope in multiplayer... The big difference between the original and this that actually made me raise an eyebrow was how "open" the area of the launch site was. There were some massive walls to the launch site in the original, and now it's all out in the open. The rocket is on the surface too, which is weird because you go around it beforehand, underground, and see it from close. It just feels really different, but as I said, that's not necessarily bad.

Voice acting... I'm glad it at least has it. The original HECU grunts always sounded like those bad guys you mentioned, and their voice acting was not top-notch either, especially in Opposing Force. ESPECIALLY in its Boot Camp. It was so cheesy.
