When two of a game's weapons are nailguns, you should probably expect players to be enthusiastic about construction. Following last year's excellent Brutalist Jam map pack, Quake mappers have reunited to release another free load of levels inspired by Brutalism and concrete. The 30 maps offer good honest fragging in everything from concrete cities to murderous mystical puzzle boxes. Honestly, I'd recommend downloading the pack even if only to see the hub level and marvel at quite how good Quake can look when made for modern PCs.
