About this game

Alex Mercer has a problem or a gift - depending on the view.

Thanks to a virus in his system he has several deadly powers and can change his appearance into any person he consumes which basically means the same thing as brutally killing the person he wants to be.

Of course Alex didn't voluntarily get this "enhancement".

Instead he was part of a genetic experiment at a company called Gentek.

Having lost his memory about what exactly happened, he is now both looking for vengeance as well as his past.

The second specimen, Elizabeth Green, on the other hand meanwhile infects more and more parts of Manhattan Island with a transmutation of the virus which converts people either into mindless zombies or brutal monsters.

Prototype is an open-world game similar to Grand Theft Auto IV where the player controls Alex through a 3rd-person-view.

He is able to freely roam about Manhattan Island with iconic scenery like Central Park and Times Square.

But instead of stealing cars and mugging old ladies, Alex feels more like going the Spider-Man route.

By sprinting against a wall, he is able to climb and jump up to the roof fast.

Thanks to his supernatural jump ability and his invulnerability to falling damage, he can then traverse the city from above instead of making his way through rush hour.

Of course monsters like hunters as well as the military have the means to reach him even up there.

To defend himself, Alex has several powers at his disposal.

He can lift heavy objects and throw them at enemies, making it easy to take down even a full-blown helicopter.

He also has the already mentioned ability to shape shift into any person he manages to grab and consume.

About Xbox One

Microsoft's Xbox One launched in 2013 alongside the PS4 and leaned heavily into backwards compatibility and subscription services like Game Pass. Because so many Xbox One owners moved to all-digital libraries, physical Xbox One cartridges — sorry, discs — in good condition are comparatively less common on the secondhand market than their PlayStation equivalents from the same era.

Gamevaro tracks Prototype for Xbox One with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.

Adding Prototype to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This XONE release dates back to 2009.

The PAL version (€25.53) is significantly cheaper than NTSC-U (€49.68) loose.

Rarity & condition

Only a handful of market sales have been tracked for Prototype, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Xbox One titles.

Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
