MechWarrior 5: Mercenaries, the first single-player focused entry in the MechWarrior franchise since a decade and a half, is due for release on December 10th for the PC platform as an Epic Games store exclusive (for a year, after that it'll be on Steam and possibly other storefronts).

The game, originally scheduled to launch in December 2018, was confirmed a long time ago to feature NVIDIA RTX raytracing and DLSS (Deep Learning Super Sampling). However, as it turns out, these features won't be actually available on launch day for MechWarrior 5: Mercenaries.
