Below there is a better look at one of the functions of the device; A function that lets you place people or things into a "time bubble" to either kill or slow down. It also looks like you can make a form of slow-field as well to make dodging enemy fire that much easier. Kind of a nice little function to have in a FPS.
I do have to say that while the main weapon function looks quite similar to other titles, *cough* BioShock *cough*, I do have to say that I am more excited for Singularity then I was back when I first saw it last year. Maybe I have changed my thought process on things, or maybe they pulled a hug change and made the game look and sound amazing to me. Who knows?
