Thats a nice deal

Looks like something fun to play with my kids. Will probably get this.

From what I read this game is dieing while it did not even release all planned DLCs.

So, basically this?

Just a niggling thing, but Fanatical is misspelled in the thread title.

Game always came across as something that would work well as a F2P sort of deal that would make its money on DLC/microtransactions.

The game is a solid "Meh". It's somewhat funny, but it was changed a lot during its long development and feels like it's lost between its early and final concepts. It has some weird co-op modes where each player controls a limb.

Does fanatical deliver it as one key or as multiple keys?

They deliver it as one key, titled OVERRIDE: MECH CITY BRAWL - SUPER CHARGED MEGA EDITION

You get the game in humble monthly bundle, worst time to release a bundle for it @fanatical :P

Edit: I ment the base game, didnt think the dlcs would matter much.

They throw the base game on HB and launch a "bundle" of the whole game as one key somewhere else...
These devs seems to be very concerned about how satisfied their costumers can get with their products...
