Unfortunately, the Quests for 'Earn to Die: Exodus' seem to be broken at the moment...
We are looking into this right now and are working hard to try and fix it asap.
I wasn't able to write this earlier as I was banned, but the Buggy Up quest doesn't work. I swear I completed the game in 51 (in-game) days starting from wednesday, but I didn't get the quest.
This is a really great old game. Lots of fun, but it's a shame about the flaws that Olinser mentioned back in 2015. I'm speaking specifically of the fuel being drained while being idle(not pressing up), and the fact that you often break through ramps instead of going up them as you should. For the later problem, this makes perfect sense if you're landing on a ramp from above after a big jump, but this happens even if you simply just try to drive onto it! Sometimes it works properly, sometimes it doesn't. I'd give this a 7 overall, but with some added polish it could have easily been an 8, 9, or even a 10.
