The next Trials release will be a mash-up with over-the-top Far Cry spin-off Blood Dragon.
Ubisoft is yet to reveal the game, although the listing also comes with a logo:
It is unclear if this is a standalone game or another expansion to Trials Fusion. Last year, Ubisoft and RedLynx launched wacky expansion Trials Fusion: Awesome Level MAX which featured a gun-toting cat riding a unicorn. That was announced at E3 2015, so we may see another announcement from Ubisoft at E3 2016 in a couple of months.
