The multiplayer beta of Uncharted 3: Drake's Deception launched on the 28th of June 2011 to all PlayStation Plus members, owners of specially marked copies of Infamous 2 and beta code holders. Statistics and levels from the beta do not carry into the full game.


Release and early issues

The beta was released on the 28th of June to Asia and Australia several hours early to account for the time zone difference. It was released to the rest of the world at approximately 2pm PDT that day. In the hours following the release, the beta was immediately reported to Naughty Dog as being filled with issues, most notably a widespread inability to connect to the servers (with an "Error initializing session manager" message), severe frame rate drops and persistent crashing. Naughty Dog disabled the beta's Facebook connection feature in an attempt to ease these problems. The beta was patched to version 1.01 at 1:30am PDT on the 29th of June, less than twelve hours after its release.[1] Further issues arose with the patch download, with several PlayStation consoles simply resetting when attempting to download.

Following early issues with Plunder, it was removed from the available gametypes and replaced with Free For All Deathmatch.

Further patches

The beta was patched to version 1.02 at 10:30pm PDT on July 5, 2011. This patch included the addition of Plunder back into the playlist, as well as the removal of Free For All Deathmatch, and the re-addition of Facebook integration. The patch also allows players to disable Uncharted TV.[2]

On July 6, 2011 the beta was patched to version 1.03, with the update fixing matchmaking issues in European regions.[3]

Patch 1.04 was released on the 8th of July 2011.[4]

Account resets

Toward the end of the beta, several player's beta accounts were reset back to rank 1, and all unlocked beta content was lost. However, Naughty Dog assured that their progress up to the reset was saved and will count towards the full game rewards.[5]

Final statistics

It was announced after the beta had ended that it had been played by a total of 1.53 million unique players. The average number of kills per player was 1,200. In total, approximately 48 billion shots were fired in over 22 million matches. Players earned a total of approximately 1.8 billion kills.[6]

Gametypes and Maps

  • Team deathmatch: Standard team deathmatch. Two teams of five face each other, and the first team to fifty kills wins. If the results are close at the end of the match, one minute of overtime is added. If the results are tied at the end of this minute, the match enters sudden death.
  • Three team deathmatch: Three teams of two face each other with a goal of twenty kills.
  • Free For All: Eight players battle each other with a goal of fifteen kills.
  • Hardcore: Standard 5 vs. 5 deathmatch, excluding features like boosters, power plays and medal kickbacks. The cargo plane sequence is also removed from the beginning of the Airstrip map, as well as the short animation being removed from the beginning of the Chateau.
  • Co-op arena: Three players have twenty minutes to complete as 10 rounds of challenges. Three gametypes are included: Survival, Gold Rush and Siege.
  • Co-op Hunter Arena: Two teams of two (2v2) are pitted against each other, one as the heroes and the other as the villains. The villains are aided by AI enemies and there goal is to stop the heroes from capturing any treasure. The villains start out weaker than the Heroes, like the AI goons. Medal Kickbacks are awarded to the Heroes for returning a piece of treasure while Hunters earn medals for obtaining kills, which allows them to pick a more powerful pirate or soldier to respawn as. After six minutes the teams are reversed. Spawn locations of the AI change throughout the match as well as more powerful gear becoming available as time goes on.
  • Co-op Adventure: Similar to Uncharted 2's Co-op Objective, but with added objectives, such as placing numerous treasures around the map.

The above gametypes were played on either the Airstrip, the Chateau, or Yemen (which was added in the final week of the beta). Co-op Adventure was played on the Syria map.


U3 1-50

The badges used for ranks in the beta.

The beta contains 47 ranks, each requiring varying amounts of XP to reach. Although early information said that the maximum rank would be 25, it was later announced that the cap was level 50.[7] This however was incorrect, and the highest possible rank is in fact 47, as the player can not accumulate more than 10,000,000XP.

Power Plays

Power plays are a means of giving a losing team an advantage, and a chance to improve their score. They can occur several times throughout a match, and can begin with as little as 5 kills between the two teams. They are accompanied by music. They last 60 seconds each.

Name Effect
Marked Man A member of the winning team (referred to as the VIP) is marked. The losing team gains extra points for killing the VIP, while the winning team gets extra points if the VIP survives.
Exposed The losing team sees the locations of all winning team members through walls and other obstacles.
Double Damage The losing team deals double damage with all attacks.
Cursed The winning team sees everyone as skeletons and friendly fire is enabled. If a member kills their own teammate, the other team earns extra points, or if a member from the losing team kills a member of the winning team they get extra points.

Treasures and Treasure Sets

Treasures are occasionally dropped when you kill an enemy. They can be picked up by pressing PlayStationTriangle and will eventually build into treasure sets, which are used to purchase character skin customizations.
