MOBAs are definitely the big thing right now, with Dota 2, League of Legends, and DC’s own Inifinite Crisis. EA has their own free-to-play addition to the genre too; Dawngate.
Dawngate is said to ‘look and feel familiar whilst offering a whole new way to experience MOBA gameplay.’ You can sign up to the beta over on the website. Take a look at the screenshots, character art for Kensu the Mistwalker, and the ‘break the meta’ trailer below.
