Battle-tested in Epic’s own games

We’re constantly looking to differentiate Unreal Engine 5 with cutting-edge technology like Lumen and Nanite—and we put the features through their paces on our own games like Fortnite before we hand them over to you, already production-tested. And because we’re game developers too, we’re always motivated to keep up with industry-standard tech like FSR 2.0, DLSS 3, and DX12.

Unreal Engine 5 comes with templates for both first- and third-person games; sample games that you can dissect, learn from, and reuse; and easy access to high-quality assets like Quixel Megascans and MetaHumans.
