I get all the prices in Pounds and it says £23.99 for the new Doom, but I fink it's $36 for Americans.

With the "20% off" voucher the site offers right now, that becomes only £19.19, which is amazing.

But is there a caveat?? I know it doesn't include any DLC or season pass with that price, but those are only multiplayer, yes? And I only want Doom for the single player campaign. Please help clarify.

Greenmangaming is generally a good site so I do trust them. You won't be able to get a refund so that is probably the only caveat from my experience.

Well, DOOM was on sale for $40 for all platforms on amazon a few weeks ago, and I just bought it on Steam for $36 during the summer sale, so this seems legit. GMG is a trustworthy sitr, and iirc "retailers" take a 30% cut of game profits, so even with the 20% voucher they're still making some money off of you.

PS: The game is incredible!

It's legit. Go for it!

Been using GMG that bit more than Steam sales. They are more legit than say G2A.
