Transformers: Fall of Cybertron

No. It's Activision.

Maybe. It's a week-long thing, so those on 25% have a chance of deeper discounts later. Just be patient. Otherwise, wait until it goes on sale again. The Transformers games go on sale pretty frequently.

saw it for like 10€ on some cd-key site not too long ago

Activision game.

maybe. they do daily deals (unless everybody forgotten about those)
im hoping it goes on sale too. i want War for Cybertron.

I believe it's much cheaper at times on amazon and GMG.

It'll be on sale again another time if you can wait.

Side note: I really enjoyed this game. Alot of original voice actors make it a great trip dowm memory lane. And it played real sweet too!
