If you're a fan of action-focused roguelikes with plenty of ridiculous combos to experiment with, you might be glad to hear that Enter the Gungeon is now entirely free to grab. Simply head on over to the Epic Games Store, log into your account, and you'll be able to claim your copy in no time.
The one catch, as always, is that the promotion will only last for two weeks. As such, make sure to grab your copy before Enter the Gungeon goes away on June 20th. You don't even need to install it, just add it to your account and you're good to go.
As for whether Enter the Gungeon is worth your time and effort, I would say the answer is a definitive yes. Much like The Binding of Isaac, Enter the Gungeon is remarkably fair as it allows you to dodge every single projectile from every single enemy and boss in the entire game, so your success or failure really is down to you and your own skills. Combine this with some satisfying combat mechanics, a charming and pun-riddled presentation, and you've got yourself a rather enjoyable roguelike.
With that said, I'll leave you with the original launch trailer. It should give you a pretty good idea of what to expect from Enter the Gungeon. Enjoy!
