Presumably to tie in with, or advertise, the Invincible series on Amazon Prime, this part turn based strategy, part visual novel was released for free by Amazon. And it’s pretty good!
It tells a similar story to the show, but mainly from the point of view of Atom Eve, with her run-ins with useless foe Killcannon as well as family drama and love life trauma.
The visual novel bits allow you to choose various responses in conversations, some of which are only possible if you’ve levelled up the skill tree in required ways. The fights are turn based and fun, with some forward planning required for many of them.
Definitely worth playing if you’re a fan of the source material.
