Experiment 101 was founded by former members of Just Cause developer Avalanche Studios, and Biomutant, its debut title, aims to build on the familiar open-world formula by giving players the opportunity to customise their animal protagonist with different mutations, bio-mechanical body parts, and gear - affecting the stats and abilities available as they progress across the expansive, plague-ridden landscape in a bid to save the Tree of Life. The end result is a surprisingly vibrant sort of post-apocalypse, combining exploration (both on the ground and in the air) with heavily customisable gunplay, martial-arts-inspired combat, and a branching, mission-based narrative. At least some of that can be seen in publisher THQ Nordic’s nearly ten-minute-long gameplay trailer from last year. When Biomutant launches on 25th May, it’ll be available in standard edition form, alongside two special edition releases. The Collector’s Edition costs around £100 and features the game, a hero figurine, artwork, the soundtrack, and a “premium box”. There’s also a considerably more expensive Atomic Edition which, for £349.99, includes all of the above (minus the figurine), plus a “high detail” diorama, steelbook, t-shirt, and an oversized mousepad, presumably for the benefit of those struggling to contain their oversized mice.
