What a piece of garbage. Don’t play this at all cuz there’s a
place in the caverns you can actually get stuck. The doors closes on you and you can’t open them at all. It is even marked in the walkthrough. What was the guy who made thinking? My guess is nothing at all.
The mod itself is ok (some cool maps) except don’t try to figure what’s going on cuz I don’t know myself. You start in Roswell and then you end-up in a shack somewhere. Very odd.

(spoilers)
The funniest part is in the beginning where you can’t enter the vault but if you go in the bathroom right next to it, you can crawl inside using a vent. Now what where the ones who made Roswell thinking??? They keep aliens and flying saucers but can’t figure out archictecture.
Anyway enough trashtalk. I’m pissed enought has it is.
AVOID!

I played that game a while back (as far as I could).
There is a point where you fall down a chimney to enter a building.
The only exit is through a high window, you can see the ledges to reach it, but there is NO WAY to make a jump to reach them. I tried everything for several hours, this is a dead end.
5th February 2006
There are certainly no dead ends in this map addon for hl. I beat it back in 2000 when I was crazed with half-life and virtually played every mod that I could get from the Internet. There might be some quite illogical and clumsily set up progress requirements. But overall, due to the length and uniqueness of the mod, I found it quite satisfying.
12th February 2006
I found it a good mod to play but it has no warning that you have to kill things as soon as you come from the vent and you are in a little room down the stairs there are military down there so watch out.

Get the map pack off my website, dont get version 1 there is no difference apart from better compiling of the levels so they run with lower polys and the spalsh screen.
11th March 2006
I have edited the link to point to the PlanetPhillip server and also to the version that you recommend.

Feeling nostalgic and downloading this mode again. God I hope it is as good as i remember it being. Is this the mod where you see an alien Spaceship flying inside a hangar like its drunk?
2nd March 2007
There’s some strange comments here about this mod. Who needs warnings that you have to kill things? All part of the fun I reckon. And I didn’t fall down any chimneys, honest. Definitely no dead ends.

Well, it may be illogically difficult but it’s good. Very good. If you miss any pick-ups it’s even harder. The author has constructed a very non-linear gameplay that’s different to the usual stuff, and refreshing to see. Just use the old grey matter a bit more and drink less alchohol if you can’t beat it. Don’t avoid it, play it. There’s no auto saves, so don’t forget to save a named game occasionally or you will get stuck at a certain place in the game. It says so in the walkthrough, but don’t read that. This guy’s a tricky smart modder, but he’s a fellow English gentleman, so no suprise there
4/5 for original routing and no bugs.
7th June 2007
Very dull. Nearly endless corridors, then elevators to the next series of nearly endless corridors.
29th July 2007
Perhaps someone can help me. I’m right at the end of the game and cannot enter the booth with the ‘test fire’ switch in the virus room. Is this a bug or have I missed something ?
Any help would be much appreciated.
Thanks,
Ed

You have to press the safety hood buttons in a certain order. Cant tell you here as spoilers are banned (:
There was a walkthrough available via the authors website, but the site is now suspended.
I have the walkthrough available as a txt file if anybody wants me to upload to Phillip, just ask.
29th July 2007
I have sent the walkthrough to phillip anyway.

hey phillip
i see a “whats happened to a migandi” post on your forum, just thought i would let you know, i tried to renew my domain and did so but due to the useless people located abroad on the helpline i was unable to rectify the problems and decided to delete my website rather than pay the arseholes twice like i did before the other year.
you can contact me at the email address if needs be.
thanx for keeping my mods alive, i know my stuff is hard to play but i made them for die hard players who needed a hard challenge
i was gonna do a walkthrough for riot mod but as my websites gone i gave up on that idea
17th September 2007
That’s a shame. I understand about not wanting to pay twice though.
You are most welcome.
If you write it, I’ll publish it!
I’ve sent you an email.

Long and getting better level by level. The Walkthrough is helpful, the game is not straight and you have to go back long ways after switching sometimes. Some Frustation about the long ways back. But it is one ofe the mods i played to see the next interesting room, the next train an the next room… Enjoy.
30th November 2008
I might add 2 things to the author’s walkthrough:
1. in Chapter 7 (As the crow flies) you don’t have to take out the grunts using the crowbar. In the previous map there’s a Barney in the toilet, you can take his pistol.
2. in the final chapter (Virus Control) you don’t have to guess the secret combination, instead you can try and press the virus control button from behind, by jumping off the green platform in the middle. It’s hard, but not impossible. You just have to be careful afterward, cus the explosion takes a lot of your health.
About past experiences: I, too, have played this way back, actually I was wondering which one was left of the 5 mods I had back in 2000 or so. This truly is another classic.
About the mod itself: everyone who said this mod can’t be finished, you’re wrong. If you get stuck, try again from different saves, there’s always a way out.
The only thing it’s truly missing is great puzzles. Most of them was find the button or find the door opened by some button. Exploration is rewarded, plus there’s hidden health ‘n batteries in a lot of breakable stuff, too (like a radio or tv, for example, but you didn’t hear that from me..). The story was ok, but I would have wanted a lot more feeling of Roswell.. Hmm, what else? Ah, no bugs! I can’t imagine why the first mods that came to life back then were oh so thoroughly tested compared to the newer ones..
I’ve enjoyed replaying this a lot, maybe even more, because it was familiar. The first time was pretty hard, for a beginner. It’s very non linear, which is hard to come by these days, a big plus! Except the backward tram ride was a bit boring. It’s got interesting levels like the assassins and the cabins (my favourite back then), the double timed doors (which gave me a hard time even today) and the ‘jump from window to window in a tight vertical space’ thing (I love everything related to city blocks in hl). The gameplay is great, can’t complain there. The mapping is ok, some sizes are odd in the beginning and the ‘comma like’ walls were a little confusing (I’m referring to the round walls which hide plenty of alien grunts) plus I could sense an overuse of alien grunts all through the mod. But you get to fight a lot of them with Barney(s) by your side, which is always a nice feeling
Although playing this mod brought back a lot of good memories, it also made me realise just how long I’ve been playing hl. And even though I have lived this mod to the fullest – a bit of laughter, a bit of cursing, a lot of smiling when remembering several parts and how I enjoyed them and how I was still enjoying them now – I have also noticed the every day engine glitches (like buggy doors and sometimes poor AI) and the every day mapping imperfections (like small jiggling textures, or bad lighting, or as I said before, odd sizing). And for the first time in my life I saw myself like the others see me when I tell them I’m still playing hl1 10 times more than any other game. And I thought to myself I have to move on.. which is hard, because I know great stories and gameplay is really hard to find, but I can start with the next best thing: the rest of the hl series which I’ve postponed so many times because of the great number of mods for hl1
God bless this site and thanks for letting me be melancholic.
PS: Play this mod right now!
