Create a behemoth and let it loose on other beasties in Monster Mayhem: Build and Battle. As the title suggests, a key feature in Monster Mayhem is the custom creature creator, allowing you to freely adjust size, weight, skin type, elemental affiliation, horn styles, and an assortment of other individual body parts. Once you've named your scary spawn, it's time to rumble though the idyllic city of Happy Valley, defending it from other monsters in a series of one-on-one battles that are structured like those in a traditional fighting game. Earn experience points so you can advance in level and upgrade your monster's core abilities.
