Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
13 of 15 markets; the rest we haven't asked for this title, not markets where it is unavailable.
Availability
We put this game to every storefront we collect. A market that answered not sold has told us something about the game; a market we never asked has not, and the two are never drawn the same.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 2.71/day in the week to Sep 3 → 6/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,420 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

13 on sale2 answered “not sold”0 we did not ask
The 2 “not sold” markets are read from the Steam price pass of Sep 7: that day the store answered for this game elsewhere and gave no price in those. The 13 priced markets are the same rows as the table above — each the latest price we hold, dated here when it is older than that pass. The 0 marked “not asked” were not put to this store at all — either it has no storefront there or we do not collect it yet, and neither is a statement about the game. A refusal is a refusal on one day; a store can list a title again tomorrow.

Muy buena para su tiempo y su costo. Obra Maestra.
desperately needs an update or at least a disclaimer that this game will NOT run on modern hardware without a workaround. with that said, prototype is an incredibly fun game. the aesthetic alone is something im obsessed with, and while the story is a bit of a mess it doesnt matter too much because i dont care! its classic overpowered chosen one MC with amnesia tries to piece together his dark and mysterious past, theres just enough pieces for things to probably make sense if you care about it but even if you ignore the story its still really fun to go around stabbing zombies and blowing up cops while you backflip off a skyscraper into oncoming traffic and slaughter countless innocent civilians. the stealth sections are decent, the combat is incredibly fun and engaging, the progression system is just as if not more engaging, and (most) of the boss fights are cool as hell. i have some really fond memories of picking up a car and seeing how many civilians i can punt with it in a row when i was a kid, and replaying it as an adult i can confirm its still just as fun as i remember. the graphics are a bit dated, but the game literally came out in 2009 and i honestly think it looks incredible considering the time period. highly worth the purchase if youre willing to use one of the many guides on how to get it running properly, though generally id wait for it to go on sale instead of getting it at full price
无法云存储,每次都要重新开始,自己的存档也放不进去。
Underrated. Pure nostalgia for me and still holds up great even in modern gaming.

好,部分指引做的不太好,但毕竟是一个老游戏,就当时来说整体其实非常棒了
