Since people have already 100% it on the day one release, is this game fairly short?   How long do it take to get to 100%?   I am mostly curious as I love the look, concept and gameplay of the demo but worry $15 maybe steep for something that maybe 5 hours long.  Then again, I loved Limbo.

This last boss is hard as fuuuuuuuck. And I beat Hitler on Super Hard in Bionic Commando: Rearmed.

No it's not. Use the normal weapon, not the saw.

I don't understand why they would tell you to use the saw. It's ridiculous. The one weapon you should absolutely not use they tell you to use.

i've played just a little and am already at 50% completion... goddammit, I really like this game...  
need... more... shadow... planet...

I find 4-5 hours for a $10-15 game perfectly acceptable. Most $60 games are only 6 hours in comparison. Limbo being under 2 hours for that price was a kick to the balls though.

I don't remember that....

I used the saw. The whole time. I didn't even attempt to use anything else. Sigh.

5-10 hours is probably enough to tide me over until Deus Ex comes out. I'm still a little wary of paying $15, though. Yes, I'm cheap. Still, I paid more for a used copy of Modern Warfare 2, and the single-player in that isn't much longer than six hours... Damn it, I'm going to have to get it.
