I'm not entirely sure you can really judge gameplay based on a handful of screenshots.
Extensively? No. However, with the info that's been released joined with various screenshots, I can make a few impressions off of that alone.
I can already tell the game is TPS with some standard mechanics in play, which is my main gripe since I would rather see RAD do something new instead of making a game in a genre that's rather over-saturated right now.
