This looks okay, but there already is a remake of Decay for Half-Life in which you can even switch between the characters like in the original game!
The intention of this mod is to remake the original game into a single-player experience, not to do yet another 1:1 port of the game to PC.
Well, this is a nice little Demo that indeed turns the HL Decay coop experience into a Single Player one.
So I guess it’s worth it. Also, the whole 2-3 maps felt quite polished and professional.
My only and definitive complaint is the length of the mod which is quite short. I mean if you took the bother of turning it into a SP why not make a proper mod and make it longer?
That would be cool.

There is actually a full version of Solo Mission currently being developed. This is just a short demo
I found this mod very good, ideal for those who haven’t played half life decay, it’s very successful

I very polished and fun demo. It’s going to be interesting to see how these levels will be redesigned to fit single player. I look forward to the full release!
Pretty damn good, played it like 2 or 3 times, very fun, gotta love the map redesigns, I’m rotting to play the full version someday 😛
