On a Rail Uncut

Description
Text FAMGUY1 (real name: Chon Kemp, A.K.A. DIGITAL SPORTS - now the Lead Level Designer for Black Mesa) old project to finish "uncutting" Black Mesa. This mod extends Black Mesa's On a Rail back to the length of the chapter in HL1, by seamlessly adding 4 new maps in between the existing Black Mesa maps.

=======

Black Mesa cut "On a Rail" extremely heavily, due to its unpopularity and confusing design in the original Half-Life. On a Rail was 10 maps in HL1, and is represented by a mere 3 maps in Black Mesa. While Black Mesa's version of OaR has been well received for its less confusing design and greater focus, some fans (such as myself!) might have wanted to see the original HL1 maps given the Black Mesa treatment. Well, here they are! This is my attempt at restoring the missing maps from "On a Rail" to Black Mesa. Note that these maps are very far from straight 1:1 remakes. I've attempted to follow Black Mesa's redesigning principles on the maps which I've remade. This means that areas which were poorly designed in HL1 were streamlined and simplified in this remake, and areas which had potential for expansion have been expanded. The aim of the project is to maintain consistency with both Black Mesa and Half-Life 1, and like ST Uncut, to maintain flawless integration with Black Mesa's current offerings.

THIS MOD HAS BEEN LEFT UNFINISHED. I was hired onto the Black Mesa team in September 2013, and I put this mod on hold in order to invest time into my real commitments with Crowbar Collective. However, the mod is finished enough that it can still serve as a worthy addition to the game - but I just wanted people who play this to be aware that it is not 100%. Probably more like 60%.

Will this be added to the official update, just like the "Surface Tension" maps were?

it's cool to re-live the levels but overall I agree with their decision to cut this segment. It's clunky and just way too long

Really fun to play for the first time. Then after that you realize why these maps were cut. I'd recommend playing these after beating Black Mesa normally, as this has a large difficulty spike and very confusing layout, even if *somewhat* better than the original On A Rail in Half Life.

This was always my favorite chapter in the original game. Navigating those narrow tunnels deep underground was appropriately oppressive and claustrophobic, and it had an almost perfect blend of alien and marine enemies. Launching the rocket was a triumphant moment, the first real victory since reaching the surface in We've Got Hostiles. This mod elevates this chapter to the same pinnacle of achievement as the rest of the game. I would love to see it finished some day. :bms_crowbar:

Would normally recommend this mod but there is a level when you have to disable rail security and what happens if you forget the rail car is it glitches out. You can't cross the electrified beams and the door will not open causing you to have to noclip through. So that was a real pissoff.

Shit man, this is awesome. On a Rail was annoying as hell but really fun at the same time. Tons of stuff going on at once ya know? Glad to see this exists.

I've never been so happy to see the worst level ever

I completed the definitive edition of BM before playing through "the definitive OaR" mod. I only experienced an issue on the last map, the one where Gordon launches the rocket carrying the satellite. Loading any saves, quick or normal, resulted in the AI being disabled (this came up as an "AI disabled" message on the screen). Restarting the game did not solve this. As I had already completed this map during my original play-through, I didn't investigate a solution. Other than this (critical) error, the mod is a functional addition to the base BM game.

Well done on a brilliant remake/upgrade, even if it's only 60%.Although I understand the pov of the BM devs in slashing OaR, the changes go way further than simple alterations. I think that there should be a prominent notice on the game's Steam homepage, stating how much and why OaR has been cut, and advising players to subscribe to ""OaR uncut or "the definitive OaR", if they want something close to the original experience. Or the mod is incorporated, as an option, into the main game.
