The Epic Games Store has been giving away various games for a long time. For example, until May 27 at 18:00 (MSK), you can claim the basketball sports sim NBA 2K21 for free.
It looks like the action-adventure game Rise of the Tomb Raider will be given away in the EGS today. This game about tomb raider Lara Croft was released in 2015.
Reddit user KekanKok reported that this game would be included in the giveaway. They posted a screenshot of a tweet from the Epic Games Twitter account. The screenshot features a checkmark, which should confirm the authenticity of the account (unless it was added using an image editor).
If this is indeed true, the giveaway of Rise of the Tomb Raider: 20 Year Celebration will begin today. This edition of the game includes all previously released add-ons.
