Estimated lifetime sales and revenue
| Low | Medium | High | |
|---|---|---|---|

Steam doesn't publish sales. These estimates multiply the number of reviews by a factor that depends on the release year (the Boxleiter method). Net revenue is what's left of list price × sales after refunds, regional pricing, discounts, sales tax and Steam's 30% cut, before any publisher's share. Treat them as a ballpark for comparing games, not as reported figures.

You're outnumbered, low on ammunition and the paranoia sets in. This is an action horror-world where enemies get power-ups and you don’t.From the Steam store page
