Just browsing the net and found that someone has developed a throw-able fire extinguisher. Sounds pretty neat and from the video below it looks like it's effective.
I've been playing a reasonable amount of Crysis 2 lately and at first I did really think it was better than the original but after a while I really missed the freedom and beautiful sunsets of crysis. The multiplayer aspect of Crysis 2 hands down beats Crysis for me but the single player just seems very 'stagey' and linear.
Crysis, while being linear, allowed the player more ways to beat certain tasks and basically provided more freedom than Crysis 2 does. Also in the original I loved blowing stuff up, the physics were pretty decent. But with Crysis 2 I haven't even noticed any explosions where I thought "holy shit, thats good". I doubt I'll beat the single player again after one play through, but the multiplayer is a keeper.
