Episode Two includes a reporting mechanism which tells us details about how people are playing the game. We're sharing the data we collect because we think people will find it interesting, and because we expect to spot emergent problems earlier, and ultimately build better products and experiences as a result.

These statistics show how long players took to complete Episode Two, average deaths per map, which advanced rendering options were enabled, and a whole lot more. They even have color-coded "topographical" maps that show where in the map most players died.

Unfortunately, there doesn't appear to be any Portal-specific data.

the 'death maps' are really interesting, people are dying in really silly places

It still amazes me how many people play it on medium, I went straight into hard and found it reasonably easy

And only 60% of people 'met the hunters'.... truely pathetic
