There's been a lot of buzz about the latest addition to GTA Online, known as After Hours, with a brand new vibrant nightclub scene added to the game. Unfortunately for those of us who prefer single player, there hasn't been any GTA V DLC for many many years. This new mod, however, brings a lot of the new nightclub features to GTA V single player.
JediJosh920's After Hours mod brings the fully scripted nightclub experience, with world-class DJ's Solomun, Tales of us, Dixon and The Black Madonna providing the soundtrack to a night of dancing, drinking and even the ability to customize the nightclub with styles, names, and choice of DJ. It fits perfectly into the single player experience, so if you've wanted some new, somewhat official content for GTA V single player, this mod is for you.
There's even a few Easter Eggs to find in there, although due warning, if you do play online, make sure you don't have this or any other mod installed, as the game often bans players for using mods, and given this one touches GTA Online content, it's no doubt better to be safe than sorry.
