I really enjoyed this one. A few puzzles, a variety of combat situations and some nice level design. I particualrly enjoyed the section shown in image 12.
The A.I. semed a little strange at times with some enemies just standing still but don’t forget this was a demo, so things would have improved.
It’s a shame that this was never finished.
5 Words Or Less Review
Nice trip down memory lane
Agreed a fantastic mod. Try it out people!
it crashs and loops when I reload, I kill the first headcrab and zombie but at anytime I reload it locks up and audio goes into a loop? playing open gl and steam. any ideas?
I am really itching to kill everything hehe, am willing yet unable. sniffle sniffle….
awesome mod.
…Is this still being worked on, I just noticed that the demo was released in 2004
i dont think it likes vista, tried software mode and different settings. the 9m kills it, the m16 kills it, the desert eagle works till I run out of ammo. oh, well.maybe one day.
try direct 3D i’m also on Vista and it runs fine for me. 😉
If this demo was released in 2004 where has it been for last 5 years?
It’s a shame it was never finished, as it stands it goes no where and far too short to have much meaningful gameplay. I am glad I did not play is back in 2004 being so full of promise I would have felt right pissed-off waiting all this time for the completed mod.
Give it a play through for old time sake.
Nostalgia isn’t what it used to be. The level design was somewhere between very good and excellent for me.
However, I found the whole thing was kinda “ordinary”.
What I’d like to see is an over-the-top retro-bizarre nod to good ole HL1 – perhaps a group of drug-crazed pipe-smoking nuns on the rampage (this is just an example – mutant giraffes would serve equally well).
hey your were right d3d worked even at 1024. I never thought about that setting. thanks.
I have killed many and many more will die. but, they might have to wait till the weekend. hehe.
NOTE! Phillip the download Link to direct download is broken. pak0.pak comes ruined, every time its downloaded. Gonna go check filefront now. Maybe that’ll work
I just tested the PP direct downlaod and everything was fine for me. Did it break when you opened the file or when you tried to play it?
Download works for me.This demo is pretty good for its age.A bit confusing in places.Good for a rainy day play.
andyb, do you have a lot of rain where you are?
Why yes I do :p It’s raining now so I’m about to try another map
Like Philip said, it’s a real shame this wasn’t finished, but it was fun for what it was.
In this post HL2 world it’s nice to see that HL1 mods can still be really enjoyable…..

Nice little demo, but so short 🙁 Would be nice to know what happened after that demo was released.
are you sure that this mod wasnt t this finished? because in the mod site there are no new about that
it was fun even if it was hard to figure out how to get it to play. I will say, I left nothing alive. a job well done. hehe
I’m actually the level designer from this mod’s dev team (you dont have to believe me but its true), I built this demo to try muster some interest from developers because my development team abandoned it for reasons I don’t fully understand.
Now that I see that people actually enjoyed it, I’m very sad we were unable to finish, I built a bunch of levels for it, including Black Mesa Hospital, Nursury, parking lots blah blah
Very glad you guys liked it and once again very sorry it was never finished, at that time (16 years old) I just didnt have the energy to try finish it myself.
Pretty demo of an never-finished mod it seems, right guys?
I liked the OF style much, but it really seemed to me that this is indeed only demo, showing not the best of the maybe-complete-mod …someday
Pro’s:
-Decent design
-Good balance
-Nice puzzles
Con’s:
-Less combat
-Only indoor (some poor designs like grey walls only)
Fun demo. I like that I have to fight Black Mesa security officers. The puzzles are good.

A very good demo at least, simple puzzles, less combat but in a challenging way and yes, challenging. I underestimated the security guards at my first try. Map layout seems a little bit bland. That sums up my review to this demo
