Here are some screenshots. First, here are parts of the larger of the three levels,
and here is another part of that level, where water effects are turned on maximum (both reflection and refraction, and glare),
Here is the medium-sized level,
which has a very different theme to it. You can also see a bot charging towards me there. Finally, here is the smaller level,
and here in that level is a ferocious squirrel on the attack,
(the squirrel model is from the Yo Frankie game).
What the screenshots can't show is that playing a first person shooter in a web browser (without any plugins!) is an interesting experience, I guess because it isn't a common thing yet. Try it :)
