A couple of years ago many people (including myself) asked Necromanthus to update his online demo Deus Ex Reloaded.

Now I tried again:

Anyone here interested?

*claps hands* Purely amazing. I'm not sure if there is any use for a browser version though. A cool proof of concept.
I didn't find the commando too tough at all. Generally I won't have taken him on with a low skill on the pistol and no accuracy mods. Commando died with 6 shots to the head while crouched at fairly close range. Not sure if this demo had body zones. Found the sniper rifle later, but found no more enemies too shoot.

I think it's the best way to promote a game.
