Tonight, the A.C.I.B. has need of your special abilities to counter a new threat to civilisation. You have been given a rendez-vous in the warehouse district of the city to receive your mission briefing.

I don't understand why this doesn't work under the Linux version of Half-Life, it doesn't seem to have any Windows specific stuff in it.

I see no reason this doesn't deserve a straight 10 out of 10.

The mod starts off with a simple intro that clearly lays out the plot and starts you off. The rest of the game is going through a fun and carefully built facility. Designs were good and going through the mod was highly enjoyable.

The creator even put in the extra little effort to put some personality behind the main villain and some of the allies you come across in the game. Certain parts of the mod were especially flashy and detailed and I loved every second of it.

I found no problems whatsoever with the mod apart from a single texture error that just caused a small surface to flash. This is bug free and well crafted, so kudos to you and job well done. I loved this.

Nothing special. No new models, sounds, or skins but the level design is fairly decent. Several times during the mission, the player is forced to noclip in order to continue as there are no conceivable ways of navigating the obstacle in question or doors are locked with no other possible avenues. The mission is topped off with a ridiculously difficult boss battle that will take you a score of tries to figure out (or a couple of minutes using god mode).
5 out of 10 MAX

This one is definitely one of the best ones to come from hl modding scene. It does once again manage to give a unique location that oozes good texture usage. Theres nothing custom made, its just so well used. Each area is noticeably different and it has the coolest opening to a mod I’ve seen so far. Rain, thunder, derelict buildings, secret base, mission briefing. Awesome.
As I stated the locale changes drastically, we go to a night time cable car area, to a frosty mountain top.
Marble interior then changes to labs and each area feels like people actually live/work here.
Its a mod that can also tell a story through action, which is what a good Half-Life modder should be able to do.
While HL has no cutscenes there was a good use of barney and scientist dialogue lines and briefing text. This modder knows what hes doing.
Valve is fond of vent crawling and puzzles, this mod has a minimal of that but thats ok.

My only real complaint is the length could have been longer but I can’t fault it for that.
