Grand Theft Auto V has a whole new way to play that's sure to appeal to PUBG and Fortnite fans, thanks to modder Theaetik. Theaetik has created Complex Control, which transforms the game into a single-player battle royale/roguelite shooter. It's available now on PC, and promises "high replayability and variety...it feels as though there's always something new to experience every run."

Complex Control features 70 unique characters with color-matched weapons and vehicles. It tasks the player with controlling and surviving a deadly zone populated with AI parachuting from the sky or driving right towards you. There are more than 50 unique abilities (with cooldowns), and players can choose from a pre-made set of characters with their own weapons, abilities, and vehicles as they try to survive. You progress your own character until they die or until you trade them.
