Ausgamers:
Visually, Singularity is shaping up to look very impressive. Some of the retro, cold-war era scenes reminded me a lot of scenes from BioShock - it has a similar look and feel. The effects are similarly impressive and there's a lot of attention to detail in the environments, which are constantly changing - things like wallpaper deterioration really add to the feeling you're in a crumbling research facility and flitting around through time.
Singularity will have multiplayer, but - as always seems to be the norm at these events - no details were forthcoming. I get the feeling it will have a sort of a Fracture feel to it though - regular FPS style, but instead of raising and lowering the ground you'll be able to move parts of the environment back and forward through time to create a vaguely similar experience.
Overall - it's looking neat. The story seems the tiniest bit contrived, but if you can overlook that it looks like a compelling gameplay experience. The big question is whether the time manipulation will be enough to distinguish it from the plethora of other FPS titles out there. Our verdict is that it looks promising but we want to see more information - particularly about multiplayer!
