In short, just go to Google Play and download it, because Warhammer: Doomwheel is currently free on Android.
Games Workshop games can be a bit off-putting to casual gamers, but Warhammer: Doomwheel is different. Instead of rolling dice and shuffling orcs strategically you have to barrel through a Mad Max-esque wasteland killing chumps with your rolling Doomwheel.
The game is a straightforward arcade romp in which the aim is just to get as far as you can, destroying as many lives as you can. In a cycle that will be familiar to anybody who has played a game in the last five years, you incrementally enhance your Doomwheel along the way, allowing you to take on incrementally tougher environments.
Warhammer: Doomwheel was a finalist in the Casual Connect 2017 indie game contest, and the winner of the East Coast Game Conference award. Get it here.
