You have chosen or been chosen to enter this thread which is great. With everyone working on games like Blue Shift and Opposing Force, I thought I would give a shot recreating Decay. I am quite rusty (I haven’t made any source mods since 2007) and I have nothing to show for it yet, but this post will serve as a design document of sorts, so it is a start.
Decay is a mostly forgotten or ignored, yet still a canon expansion of Half-Life series. It had too many problems that sucked any joy out of playing it and thats ignoring the fact it was never officially released to PC.
First of all, Half-Life games, at their core, are relatively fast paced games. This game were not. This game was designed specifically as a co-op game and finding other players to play with was bothersome at best at the time. In the end, it is “RUN THINK SHOOT LIVE” not “run, think, shoot, switch to the other character, shoot again, think again, switch again, run a little more, shoot, switch, shoot again and think”. What I mean by that is, non-optional co-op mechanic of this game ruined it.
Also, the beginning and the end of the game does not fit at all with the other games in the series. In the other games, the beginning starts with a tram ride (with the exception of Opposing Force, because arriving by another method makes more sense there because you are playing as a soldier) and it end with a Gman speech (witch the exception of Blue Shift, as it was explained you were out of Gman’s reach) Instead, in this game it ends with “We did it” line, which I found to be a bit anticlimactic.
So while recreating this game, I would make it solely singleplayer and I would tweak the beginning and the end a bit.
Protagonist will be Gina Cross, as it is a more established character unlike Colette Green, who wasn’t even even mentioned until this point. Colette Green would be an NPC, much like Alyx. Game would start with a very short tram ride, where Colette Green is already waiting for you (who is a pre-scripted NPC who shares much of her animation with Alyx), and at the end with a speaking Gman.
In the begginning of the game, there would be an issue with Colette Green’s HEV suit and do the the issues Black Mesa faces that morning, she wouldn’t be able to wear it, so aside from a few missions, she wouldn’t tag along. Instead she would stay with and protect Richard Keller as it makes a lot more sense.
In the end, where you are being teleported from place to place, you end up in front of Keller, you hear the “we did it” line from him, but other scientists in the room say “thats great, now we need to get out of this place it isn’t safe”, Colette Green says there is an issue with Gina (player) but at the last second you are being teleported again to several other places and you end up near Gman, who gives this line:
“Cleverly done, Miss Cross, but you’re not supposed to be here. As a matter of fact, you’re not. Get back where you belong, and forget about all this, until we meet again.” (wich is a cut line)
You end up with Richard Keller and Colette Green again and you will escape much like Blue Shift ending.
I would appreciate any opinions, as anything would be better than the original game we got. While the story was nice enough (even though it made no sense at times), gameplay was lacking.
