Horizon Chase Turbo is a very highly rated retro racing game from developer AQUIRIS and today it sees a huge free upgrade. This is to celebrate the 7th anniversary of the franchise.
If you've not played it before, it's directly inspired by a bunch of different classic racers from the 80s and 90s like Out Run, Lotus Turbo Challenge, Top Gear (SNES), Rush and plenty more. This is a straight to the point arcade racer with no extra fluff, just you and the track.
The Adventure game mode update will bring with it a series of five challenges available for each of the 34 cars in the game, totaling 170 different races to beat. You also get a new skin for each of the cars in the game, as a reward for completing each adventure.
Sounds like a pretty sweet free update!
