Company of Heroes 2 and its DLC Ardennes Assault both free on Steam til May 30th 1pm Eastern.
The CoH2 Case Blue DLC is free if you sign up for a newsletter at
https://giveaway.companyofheroes.com/en/register. Apparently you can skip the newsletter by just entering your email (fake ones may work, too), accepting the Sega key redemption, then closing the window (without confirming your name and email). If you’re feeling crazy (for a free games thread), you can buy the CoH2 Master Collection to round up the rest of the DLCs. It’s $5.56,
an all-time low, minus a bit for owning Case Blue (which is not well reviewed on Steam, so it’s really only worth claiming to make this bundle cheaper).
Little Nightmares free on Steam til May 30th 1pm Eastern.
