It Takes Two

It Takes Two remains a gold standard for pure co-op gameplay, having won multiple Game of the Year awards, including The Game Awards 2021 and the 25th Annual D.I.C.E. Awards. Hazelight Studios' platformer uniquely requires two players at all times, with each level introducing new mechanics that necessitate constant collaboration. The game was praised by critics for its cooperative design, mechanical variety, creativity, and the strong connection between its gameplay and story. By April 2026, the game had sold over 30 million units, making it one of the best-selling video games.
