Is this actually online anywhere that it can be tried?
The video mentions enscripten and hacks.mozilla, but neither site contains any information about this at all.

Did you click the link to this page?

You'll need Firefox 22 so, currently, a Nightly build from

Once you've got that, you can either try one of their benchmarks:

(Note: BananaBench runs with a fixed time step to make JS execution deterministic, so game speed will run fast/slow, depending on your hardware/browser.)

...or you can download emscripten and compile something of your own:

(Make sure you read the instructions on enabling asm.js mode in the optimization section of the emscripten tutorial)

James Long has also whipped up a fork of LLJS that'll compile to asm.js as he explains here:,-Now-Available-?hn

If I'm not mistaken, that links off to bananabread - which as far as I can tell uses its own engine. But I can't find anywhere that allows users to try the Unreal engine in-browser
