Hello,
This is new updates:
1) Character screen, called ADriver, part of Garage where you choosing your avatar, is now additionally customized, you can now take a closer look at your selected character. It's a new button added:

Here is how it looks in practice:
Along with over 33 characters (extended over time from initial 20 in previous patches), there will be more in future, also more female chars and other different types of characters (in latter on updates from 1.x+ versions).
2) ADrivers are now buyable, you starting with the one free avatar, and during the game, when you reach more AD$, you can buy new characters and start collecting ADrivers. In early versions, they are all playable, but now you need to buy them in order to use them.
3) Some design tunings to the Player's Information Overview screen, like better-styled Reward Icon and some other fine-tunings:

;
4) Nitro action was smoothed, in some of the previous updates, there was some issue that prevents the player from using nitro, no matter the tank isn't empty. Now, this is fine-tuned and the player can use nitro any time, for longer or shorten boosts:

5) Character bio's for all 33 characters were written up, so you can find some cool stuff about their history and overall relations to the Arizona Derby competitions and bosses.
6) ADriver selection bug fixes before it wasn't saving correctly if you choose a character and get into the menu and change it and get back. Now all saving and loading exact characters you selected for the race.
Also, initial character when you loading Arizona Derby will be your chosen ADriver not one which came by default.

7) Other character polishing and fixing of the ADriver menu, little imperfection since it's way too complex interactions and options.
8) Fixed some tutorial sound at ADrone menu (under ADriver) which makes tutorial voiceover continue playing if you back from that menu and tutorial voice still playing (and interlace with other sounds FX). So now this part will not bring sound inconsistency anymore:

9) Adding over 50 exciting voiceovers for character selection and overall improved ADriver menu looks and sounds like this (with chararacter bio's included):
That's all for today folks, str8 off-roads!
