What's this app's name?

May 21, 2015
I've been having a lot of trouble trying to find this game that I downloaded a long time ago, I believe over 3-4 years ago.

I've searched through every possible means I have, key words, app store history, cropped images and I've had no luck what so ever. (Attached an image below, this is the only one I have since I thought it was pretty funny at the time and took a screen shot of it)

It was strategy/turn based game with mechs and I think had the title of "War of .... " or "Battle of ....", but I can't find the last word for the title.

Sorry If this is the wrong place to post, but any help would be greatly appreciated >.<
