Yakuza 0? Yeah, we’re gonna need at least a dozen Kiryus and Majimas running around Kamurocho. Super Mario Odyssey? Add 15 more Marios, please. Heck, just add as many players to every game ever and you’re bound to improve on it in same way. The Witcher 3 would be hilarious as would, of course, something like Bayonetta. As far as I know it's not possible, however, there were some talented modders a while back who got 8 player co-op working on Metropolis in Halo 2 Vista, so there may be hope yet. It’s got me thinking what else would be improved (or at least changed considerably) by putting the emphasis on multiplayer where, frankly, we shouldn’t be playing mod. Just imagine everyone trying to speedrun through the game at once, whilst simultaneously sabotaging everyone’s run. Sure, it’s probably not going to be the next Fortnite, but it could certainly kill an afternoon or twelve. The Portal 2 multiplayer mod is still in its very early stages and is prone to crashing – but could just as easily be planting seeds of success. If my math is correct – and the mod creator’s is too – that’s 66 portals for the game to work through. It was released before the Blastacular pack and Auto-Updates 4 and 5 were released and therefore does not include them. It was released on July 5, 2005, for 19.99 and allowed players without access to Xbox Live to download the additional maps and Auto-Updates for the game.

Having said that, the sheer possibilities of that many portals flying about hurts my brain. The Halo 2 Multiplayer Map Pack is a downloadable content (DLC) collection for Halo 2. Not only is it available to use within the game’s co-op stages, you’ll be able to tag along with GlaDOS, plus 32 others, and, theoretically, complete the entire campaign together. There's a way to play Halo 2 coop mode of 2 players or more also.
