Oh Baby Kart is free. This add-on opens up the rest of it.

THE FULL GAUNTLET

A season of stops. Pick your route: a race, a detour for extra scrap, a duel with the rival, a deal, or the pit. After every race you draft one of three cards, and they stay with you for the whole run. Three strikes and you're dropped. The Full Game gives you all three acts, the FINAL against the rival, and then ENDLESS: no more cards, faster bots every stop, how deep can you go.

UNLIMITED QUICK RUNS

Random seeds, as many runs as you like, ranked on the all-time quick board. Without the add-on you get one Daily run a day.

LOCAL SPLIT-SCREEN

Race your friends on one PC.

PUBLISH TO THE WORKSHOP
