I just wish it had useful info that didn't conflict, like when they talk about health incorrectly (16%-50% is yellow and WALKING SLOWER is not right, thanks) and then reference pills and 40%+ being healthy speed...
Thanks! The website is fairly new. We try to give the most detailed walkthroughs/guides/info on the web. We got tired of searching for glitches and achievements and finding half-assed guides that don't tell you everything. We have just recently updated it to include guides for all 50 original L4D achievements. Crash Course achievements are soon to come. We also recently posted the Blood Harvest Finale Tree Glitch Strategy which not many people know of. If you need to beat Blood Harvest on Expert, this is the way to do it. We'll be updating pretty frequently for a while so keep checking the site and thanks for your support.
I was worried it'd be some horrible "lemon party" thing.
Nice work. The criticisms I'm reading here are fair, but give it time. It's true, you can never find a good Expert guide or anything, so let them get everything in order and it'll probably be a pretty awesome site before long.
