EDIT: Yet another senior moment! Just realised that these are from February's offerings. Sorry.

Deus Ex 2 could be a serious candidate.

Nice. Five games that I don't own yet and three are even on my wishlist (Dark Deity, Mutazione and Gamedec).

And please don't waste your codes if it's doubled, bring it here instead: https://www.gog.com/forum/general/gogs_general_trading_thread

Dark Deity is very good, in my opinion (although it has some noticeable bugs).

FYI Mafia II Definitive Edition seems to include Mafia II Classic.

Thanks to you both for providing this info

I think we can expect Mafia III and more Legacy of Kain, Saints Row games for the next months.

They do seem quite consistent in giving away full series. Was half expecting to see Smurfs: Mission Vileaf this month. Doubt we'll see the LoK remasters anytime soon though.

A good tip is to check the list of games availables to play on amazon luna.

That 's a deal between Amazon and gog, games gave free are to promote this service, so you could see more of these given away for free in the future (not all).
