If you ever wanted to play around with so many dinosaurs that the very concept of riding a raptor starts to sound a bit mundane, you might want to check out ARK: Survival Evolved as it's currently entirely free. Simply head on over to the Epic Games Store, grab yourself a copy, and you'll be able to play whenever you want.
As you might expect, there is a bit of a time limit to this giveaway. So if you're interested, do make sure to grab ARK: Survival Evolved before June 18th, as that's when it'll be replaced by Pathway and The Escapists 2.
While you're there, it's also worth mentioning that the Samurai Shodown Neo Geo collection is free to take until June 18th. The collection features seven game: six of the mainline Samurai Shodown series, as well as a mysterious game that was never released to the public before - Samurai Shodown V Perfect. Each of the games comes with online multiplayer and ranked matches, so if you're a fan of fighting games, it's well worth checking out.
Whatever your choice may be, I hope you have fun, and I'll leave you with one of the trailers for ARK: Survival Evolved:
