Every Valve game released on Xbox 360 will now be X-Enhanced for 4K displays following a host of new updates.

Announced on Twitter by Xbox’s Larry Hyrb, this is the first batch of X-Enhanced “back compat” titles we’ve seen in months. In this group, every major Xbox 360 Valve game (outside of CS: GO and the already enhanced Portal 2) seems to be affected: Left for Dead, Left 4 Dead 2, The Orange Box and Portal: Still Alive.

Every one of these games are still beautiful on PC, and being able to experience them in higher resolution on Xbox One X is a dream come true. Left for Dead and Left for Dead 2 will surely look fantastic in a higher resolution.
