Doom 3 BFG engine is quite cumbersome, but very powerful. While working on Steel Storm 2, I was asked by Steel Storm fans if there will be anything else coming for the original game. I had plenty of time to reflect on the last development cycle. There were several really awesome opportunities we could have pursued with the original game, which at that time didn't even occurred to us.
So I came up with an idea to pursue those opportunities by making a small DLC first, and seeing how well those ideas would be received by the community, so that it could be incorporated into Special Edition of Steel Storm (if I would pursue such thing in the nearest future, based on the demand from fans).
Steel Storm DLC#2, dubbed as Forgotten Prison, will incorporate one whole new unique level with somewhat modified gameplay, filled with traps!, secrets! and puzzles!, plus all new music track for that level, plus a set of prefabs which would allow you to make your own levels with ease.
