It still happens that the community surprises its members, that's what actually explains Joshy's release the best. Resurgence is a high-quality Boom-compatible megawad with a total of 32 new maps from scratch that give you a certain Doom II feeling, just in a much larger scale. You can expect the quality to range from Scythe/Plutonia to Speed of Doom with speedrun-friendly maps overall, even some new monsters are included. The screenshots are very promising, but I'd suggest simply take a look at them yorself in the official development thread at Doomworld where you can find a link to the latest downloadable file.
