Facepunch Studios offers a developer's blog and a trailer for Deuce, an arcade tennis game "with a focus on unique characters and courts" they describe as "tennis crossed with Street Fighter." This news comes just days after their announcement of Riftlight, but this is just a prototype, and the post indicates this is not certain to be released, saying "the name is subject to change and we will most likely call it something else if we launch." Here's word on the prototype: "I wanted to make something different to other projects Facepunch has in development. I’m more of an arcade game developer so wanted to play to those strengths. I also love games with strong local multiplayer modes. Basically I want to make a game that we can play over lunch instead of FIFA." Thanks Eurogamer.
