An absolute masterpiece for the community we have here!
The mod starts calm, with a nice escape scene but quickly starts to get fully flexible.
The mapping is excellent, not very often that you see such a polished mapping in a mod, all areas where visually extremely attracting (especially the last level, I was just WOW), the lighting and the texturing is perfect and all the different areas are fit together in a nice and steady way.
The gameplay was interesting, while you miss some certain weapons, like the RA or grenades, it was very enjoyful, which is mostly cause of the very good enemy placement and some small scripted scenes. Also the areas in which you are fight are very interesting. Then end battle was really nice and I loved that little guy ^^
The puzzles were all very clear and intuitive, never had the feeling of having no clue about where to go, but also was never disappointed by too easy puzzles.
The music appears not often, but is well done. Only I missed a music part where you have to wait for the garage door to open up and defend against the coming screamers.
All in all, perfectly polished, perfectly playable and especially perfectly enjoyable mod, everyone should play it.

I got to weigh in. Yes it is a great mod, but a con that nobody has mentioned is the game’s real lack of long range weapons. No Gravity Gun, no Crossbow and no .357. This makes battles like the one at the end near the bridge, DAMN HARD. And too hard makes a player frustrated. And that’s not good. I’ll do a review later. It will score high, but lose points for the lack of balence in weapons.

Ok, the mod is polished, and it plays well. The enviroments are good, and change up nicley throughout the game. Lightning, texture, all of that looks pro. The battles are very fun as well, and the author throws some different challenges at you during the game. Some areas like the big reddish factory is such a beautiful eye-candy event, I wanted to stay in there and hang out for a while! Really, this game feels like a Valve production. Even the audio is nice, using different music than Valve’s for a nice change up.
The one drawback (as I already mentioned) is the lack of weapon balence. Nothing for long range battles, no crossbow or 357 mag. Not even a Gravity Gun to combat the combine when they throw grenades at you long range. So when in bigger long range battles like the several battles near the bridge, the player (to survive) has no choice but to stay back, take lot’s of damage, and use the 9mm pistol as a long range combator…and really that is no fun. Yes you have the Combine Pulse rifle, but that will run out of ammo quick. SMG nades run out fast as well, and really are not very good long range. So really it will come down to the pistol…just to survive.
This is a great mod, and deserves a place at the top. I’ll give it a 88, but it could of had a 98 if the weapons problem was fixed. Shame.

Got a WOW effect with this one, at least, for the intro sequence which is very well done.
You are a resistant posted in City 17 about 300 days before Freeman’s incursion. But the Combine are looking for you and your team and you must reach White Forest.
The action is good alternating combat and quiet at the right rhythm while the difficulty increase till you meet the Hunter. Mapping is excellent like a professional work. The parking map and the final one were really impressive.
Hope the team will release other mods cause masterpiece like this are too rare.

Finally got around to finishing this mod.
It’s a fun mod to play and just for sheer length it’s impressive. The environments are well presented and the level design is well thought out with lots of space reused in smart ways.
It’s challenging in some places but always fairly well balanced.
The no flashlight or sprint really got on my nerves.
I just have one beef with this mod… I’ve seen all this before. There’s nothing here that’s new with the exception of the clever Hunter recharge thingy.
With all the effort and work put into this mod, really you could just go back to the original HL2 and it’s episodes and get a similar playing experience but with more polish.
Play it but don’t expect anything to blow your mind.
