In a post today on the Stadia Blog, Stadia announced three new Free with Pro games for May, with one mystery game still to be announced next week.
This month's offerings include a variety of interesting indies.
Trine 4 - The Nightmare Prince (a series that, up until today, I honestly thought was about frogs)
Hotline Miami 2: Wrong Number (definitely not about frogs):
Floor Kids (Hard to say. Could be frogs, could be no frogs. Do frogs breakdance?):
No word yet on what the mysterious fourth game will be, but Stadia Twitter seems to strongly suspect that it will be Ark: Survival Evolved. Some pretty big frogs in that game.
