50% off with new game mode!

Hi all, to celebrate Prospekts continued improvement i've dropped the price by 50% for the next week! This includes a new game mode!

A concept ive been working on for a short while behind the scenes, this game mode challenges you to try and sneak past the combine and get to the end of the level. So far the feedback has been surprisingly positive so hop in and try it out! It will be in the Bonus Maps section of the main menu.

Also a few other bits and bobs tightening up the game in general places for new players.

I'll be on hand tonight for any new players experiencing issues with the game to try and fix them asap.

Also the Stealth Maps are kinda in beta so you may find a few issues. But so far they look pretty solid.

I play alot of HL2 mods as that's what my YouTube channel focuses on, and Proskept is a very decent mod compared to the majority.

Visually impressive, decent length, challenging and more importantly fun. Sure, it has some flaws but over all it's well worth a play.

The Year 1 Update that was released a few months ago further enhances the mod both visually and gameplay wise with whole areas redesigned.

What I love is that the creator, Rich, is still currently working on improving the mod, and there is yet another substantial update due for release soon.

Well worth playing, you'll be entertained

I really was not happy with this mod

Firstly, im not saying its all bad so hear me out untill the end. Im just saying how I thought this was in my opinion, a waste of money for me.

This game has some good aspects, infact im impressed on some visuals and level design from a mod. I would even go as far to say the level design and visuals are almost valve like, if not improved.

My problem with Prospekt is the gameplay in general. Its non-stop shooting, fighting, and annoyingly long flashback sequences. Never will you encounter a friendly NPC, or even any new NPCs or weapons. I dont even own opposing force, but I would atleast of appriceated A new weapon from the origonal opposing force, or atleast be able to use all of the half life 2 weapons, alongside the 5 you are presented with, or at least reskin the crowbar to shepards pipe wrench.

The part where you return to Xen was a nice touch, but the sequence was only for one level, and that level was extremely short, not even any Xen native creatures to fight, like bullsquid or even headcrabs. Just normal human combine soldiers. In short, its nothing like the origonal half life Xen, just a five minute filler part.

There were multiple times where the levels would change and I would spawn in stuck in a floor, or in a wall, to wich I would need to use console to noclip out. Or the fact that ammo is sparsley given out, and health kits are given out almost every corner.

I briefly mentioned this earlier, but theres also the annoying and repetative flashback scenes that happen. To sum it up quickly, The screens colors get nausiatingly inverted, and some diolauge between two, or three unnamed soldiers will play. Its mainly the same cliche stuff you would expect: "I hear of some aliens in black mesa!" "I dont believe theres aliens hah!" "Oh no the aliens killed all of us and were going to all die!" "Thats it drop the nuke! but leave three people behind for the sad moment!"

This game should not be sold for 10$ because of how sometimes broken and boring this game can get. In my opinion lower the price to something much cheaper, or just make it free.

I would not recomend to buy this game for the 10$ price, repetative story, cliché and expected plot, and lack of any immersion or interesting story.


I have seen that some of the complaints I have covered are being looked at, when some are updated and shipped out into the game, I will re-play it and make another review going off from that. As of now, I still believe in the points listed in the review.

- good graphics (enhanced shadows,..);
- good music ( reminds me of Silent Hill and Halo in some parts, which is good);
- well balanced difficulty, not too easy and not too difficult;
- overall level design is quite good, and definetly not nearly as bad as people here are saying;
- the included Bonus Episodes are fun to play and challenging;


- maybe a couple elevators too much..?;
- only standard Half Life 2 weapons (but a new update will bring new weapons in the future);
- the level design does not have the same high quality throughout the complete game;
- the story is not very good, but the original Opposing Force Storyline wasn't either,
so that's okay to me;

Overall I can say, that Prospekt is a solid addition to the Half-Life Universe.
Having in mind that this was developed by mainly one Person,
I can gladly recommend a game like this.

Honestly, I was really excited for this mod, but the level design just completley ruined it for me, The story is okay. I've always enjoyed Adrian Shepard as a character and its done pretty well here. The voice acting is sort of hit or miss. I like the Combine voices and the Marine voices are decent at most. But the level design just RUINS it for me, its always a huge open space or a tight corridor with combine after combine after combine, with reskins of weapons. It's disappointing to say the least. If you want to play it for the story and voice acting go for it, but the gameplay is very hit or miss.

It isn't Half Life 3, but this is the closest we'll get to it. Playing as Adrian Shephard again is a breath of fresh air, as most HL2 mods center Gordon Freeman as the protagonist. With the game still updating (with some impressive new levels and models coming along the way), it has shown many improvements from how the original product turned out. The music is amazing, has that certain thrill when you enter battle with the Combine forces. Voice acting wise, it is mostly good, but could use a little work on some dialogue. Graphics wise, there has been some good improvement to the lighting and some atmosphere. For now, I am looking forward in the future to play this game more, and I wish luck to the Creator to further make this game the best experience for every Half Life fan out there. Give the Creator of this game all your support, he is going to need it!

This game was rough when it was launched. The dedication of the creator for his work has turned Prospekt into a enjoyable game. There is much work to be done on it, but with time and effort, the creator can turn his work into something much more.

An awesome inspired sequel to Halflife opposing force if you wanted to know what happened to Sheppard then let me explain what happens in the beginning.
Prospekt takes place in nova Prospekt which is why you will be playing mostly indoors.

After opposing force, you beat this giant monster then get teleported to gman, after that gman seals you in a place where no harm can be done and where no harm can go to you and that's where this mod comes in.

the new stealth mode is awesome as well, you get to sneak past combine to get to the goal.

why all the negative reviews are it because you do this to all mods half-life-based. cause that's what I'm seeing. it's sad if so.

Beautiful and aesthetically pleasing structure as you travel through this game. Difficult combat along the way as you venture through a continued, and approved Half Life universe extension.

I was expecting a lot from a follow up to half life and this didn't fail me.
It's got an amazing story aswell as bonus levels, puzzles and is just an overall incredible game.

I'd say buy the other half life games or you'll not get a bit of the game as it's got similar challenges and puzzles. It is quite short so I'd suggest making more episodes like you did with half life 2.

Buy this game, It's worth it.

Looking good but had to choose "negative" because it froze my computer twice within 20 minutes therefore unplayable. Always happened during loading a saved game. Hoping for a fix. Also the support website seems offline, so no way to contact the developer.

PRO's: well optimized, looks and controls like hl2, backstory of sheperd and his squad from black mesa
CON's: level design, almost no story, almost no puzzles, terrible game flow, xen level frame skips, not enough enemy types, whole game is in hl2 themed prison, few hl references, no easter eggs, short

I was excited when this game came out knowing the half life franchise is still kicking. before i bought the game i read the reviews and thought maybe everyone who wrote a negative review played this and got there hopes up thinking it would live up to the quality of the original valve games. so i went into it open minded, knowing it wasn't going to be as polished but hoping it would still give me the half life dose i was looking for. i will say that richard seabrook did a good job for his first game, my hats off to you. but i will say it doesn't compare to half life 2 in many ways. alot of what people are saying in the reviews, has some truth to it. the story is almost nonexistent, the general flow of the game is way off, the levels are bland and unbalanced, you have to use a flashlight way to often, and throughout the entire game i had no idea what i was doing. a lot of shooting, not enough puzzles and no direction. i didn't even see any easter eggs or major references to the main character. but i will say the game is optimized well, no freezes or crashes and constant 60fps on my setup at maxed out settings. although the xen level gave me terrible frame skips for some reasons. i did complete the game in 5.5 hours so it is shorter. for how much i want to recommend this game, i simply cant. there's way to much wrong with the game-flow alone to warrant a negative review. but if you love half life and hate puzzles or having any story at all or hate a solid level design then this is the game for you. remember this for your next game Richard.

Great mod, I don't see why so many people hate this. The developer put a lot of hard work into this mod, and he did very well. Sure it has its ups and downs, but it is the best mod to come out in a while. Ignore the price, you get what you pay for. A Unique mod that was worth the money, that is activley being updated.

When I first heard about this game I thought, "FINALLY!!! VALVE IS MAKING A NEW HALF-LIFE GAME!!!!" Then I saw it wasn't MADE by Valve. I thought "Well crap. It's probably not good...." I thought wrong. The game 100% fits in with the storyline of Half-Life 2 and is done SOOO WELL. I love this game. If I was told to describe this game with only one word, I couldn't. It needs more words. More like ten! Spectactular, Amazing, Awesome, Outstanding, Wonderful, Exeptional, Marvelous, Superb, Excellent and Extordinary! This sequel is perfect as it is. Honestly, I couldn't of asked more from Rich. (I'd ask Valve for Half-Life 3 though! XD) Thanks Rich so much for this oversatisfying sequel to Half-Life: Opposing Force. And to everyone that doesn't own this game and looks at this, BUY THIS GAME!!!!
