I see this in City Interactive web:

Is much like the CryEngine, also read in an article in this website that says the company's games, City Interactive, used CryEngine any of their games

In my opinion, is much like Crysis

it's not CryEngine 3, it's Techlands Chrome Engine 4 they used for this game. Also a nice engine in my opinion (used for Nail'd and Call of Juarez)

However they announced the sequel and a yet-to-be-revealed WW2 game will use CryEngine 3.

At least CryEngine 3 is recognized thru other games
