I've got a new twist on the tower defence genre. You don't have a thing you're defending, and there are no attacking waves against whom you must set traps and turrets, and there are no towers, and it's a third-person action game because those are fun and the PC is woefully lacking in them. Rush For Glory, meanwhile, is a tower defence game.
Actually, I think what I like most about this announcement from Immanitas is that it's a new tower defence game that doesn't use the words "a new twist on" anywhere in its announcement. Take a look at the trailer:
This is by Russian indie studio Parseh Game Studio (who, er, don't seem quite finished setting up their Wordpress site), and it plays it straight. In 3D, but you're defending a base from alien invasions, over a ten-part campaign with 30 enemy types. It's planning to be released via various online stores, and is aiming for Steam with its ongoing Greenlight.
In other news, how can there not have been a game called Rush For Glory before?
