Is Rage 2 full of microtransactions or something? Why is it currently free on Epic Game Store?

@alyx Is there any game "free" that is not full of microtransactions?

@deadheat
It's not free-to-play, you can still buy it on Steam for example. Epic is just giving it away this week, as part of their every-week-a-free-game thing. But since Rage 2 is not exactly an old game, I find this really surprising.
