In the original announcement statement of Uncharted 3, it was said that, "Competitive and co-op multiplayer will return as a key ingredient to the UNCHARTED 3 package, where all of the new features we have planned will combine with our signature single-player cinematic gameplay to create a unique action-adventure multiplayer experience." 
Public reveal and betaOn the 14th of April 2011, Naughty Dog held an event where they revealed the multiplayer to a group of gaming journalists. The public reveal was held on the 18th of April, when several interviews were shown, along with the official multiplayer trailer.
The public beta was released to all PlayStation Network users on July 5, 2011. Early beta access was available to those who bought inFAMOUS 2 or had a PlayStation Plus subscription. The early access beta went live on June 28, 2011.
October early access
At E3 2011, it was announced that Subway customers in America could get early access to the full multiplayer mode in October with special codes on certain products.
- Team Deathmatch: Two teams of five square off in head-to-head combat.
- Three Team Deathmatch: Three teams of two competing in deathmatch.
- Free For All: deathmatch won by the last man standing from a field of eight players.
- Team Objective: Complete the assigned goals.
- Plunder: Capture the treasure.
- Classic: Two teams of five compete in deathmatch, except every player starts with an AK-47 and a Para 9. There are boosters but there are no medal kickbacks. This gamemode is supposed to be a throwback to the Uncharted 2 Multiplayer.
- Elimination: The first team to eliminate all the other teams players wins. No respawning. There are several rounds in one match.
- The Lab: A special playlist devoted to testing experimental game mode variations and gametypes.
- Co-op Arena: Survive the waves of soldiers
- Co-op Hunter Arena: Two teams of two fight to score three different treasures in three different chests. One team is the Heroes, who try to score as many treasures as possible, and the other is the Villains, who are assisted by AI enemies. The team as the Villains are able to choose classes that mimic AI enemies both physically and with what weapon they use, and the players use medals they obtain to unlock stronger weapon classes to defeat the Heroes.
- Co-op Adventure: Similar to Co-op Objective in Uncharted 2, Adventure has three players trying to complete a certain goal. Adventure contains co-op aspects, such as capturing treasures, that Objective did not.
- Co-Op Shade Survival: A DLC Co-Op game mode Similar to Co-op area, but instead of normal soldiers, you get shades (The fiery enemies found at the end of the Uncharted 3 campaign) to fight against. Round Objectives are the same, apart from Marked Shade (which replaces Gold Rush), in which you must take out 6 armoured shades (Marked in the same way as marked men in TDM)
Split screen multiplayer
Local split-screen for two players is available for players to participate in all modes except Free for All. Both players can log in with their own PSN ID and level up on their own account. The final multiplayer includes a feature that allows a second player to sign in with a second controller as a guest.
Power Plays are features that are activated when a team is losing by a large amount. They provide the team on top with an opportunity to maximize their cash for the match, while evening the odds for the team on the losing end of the equation and giving them the opportunity to close the gap a little.
Overtime and Sudden Death
If, at the end of a match, the scores are "too close to call", the match enters Overtime. This gives the teams more time to win the match by a margin of two or more kills. If this is not achieved, the match will enter Sudden Death, a feature similar to Elimination in Uncharted 2. In Sudden Death all player's name appear no matter where they are or what booster they're using.
If a player happens to be in a glitch, after some time they will die and if one looks at the bottom left corner of the screen it displays "The Multiplayer Gods have smote..."
BoostersAs with Uncharted 2, Boosters will feature in Uncharted 3. The effect of boosters will change with which rank the booster is at. The more a booster is used, the more it will rank up. The higher its rank, the greater it's reward.
Medal KickbacksMedals are in multiplayer. Once a certain number of medals have been earned, the player can activate a temporary enhancement. For example, the player can spawn an RPG in their hands, or vanish and respawn in a different location on the map.
- Sprinting (temporary running speed boost)
- Improved melee allows you to kick other players who are hanging next to your character on the same ledge. It also works if they are above or below you on the ledge by pressing the left stick in that direction along with a melee attack. A similar attack can be used on ladders. It is also possible to side-kick players that drop from above the particular ledge as they pass, if timed well enough.
- Return grenades to the player that threw it and being able to throw grenades while jumping.
Players can now customize their characters, with many different types and colors of clothing available for characters like Nate and Sully. Other character skins can be unlocked as well. Players are also given a custom character when they first play. This custom character can be given upgraded gear as they rank up and earn money by either killing enemy players, activating treasure chests or completing goals in game modes.
Weapons can be modified with Weapon Mods, attachments to increase their performance:
- Call Out
- Rate of Fire
- Max Ammo
- Clip Size
- Reload Speed
- Blindfire Accuracy
Note: No weapon can be modded with both Accuracy and Rate of Fire mods.
Emblem editorAccording to Naughty Dog, "If you’ve worked with emblem editors in other games, you’ll be pretty familiar with the one we’ve implemented in Uncharted 3. Our emblem editor extends the level of customization of your online profile with hundreds of decals, three layers, rotate and scale functions – you’ll see your final emblem on your character and even possibly in the environment during matches". Your emblem will also appear on the map if you are the top player in the game.
Videos and Cinema mode
The cinema feature is due to be vastly improved upon, with the addition of new features. Matches are now stored directly to the PS3 hard drive, as opposed to Uncharted 2's online storage system however for an odd reason the camera is inverted vertically so you can only use this control scheme in the beta.
In the retail version, Cinema Mode works exactly like Uncharted 2's, except players can rewind in addition to rewind from the beggining, and one can upload the matches directly to their Facebook or YouTube accounts. Additionally, Cinema Mode in Uncharted 3 is known for freezing your Playstation 3 if you rewind or fast forward.
Video uploads and Uncharted TV
Videos can now be directly uploaded to YouTube, eliminating the need for capture cards. There is a 90 second limit on video length. The best user uploaded videos will be shown at the bottom right of the multiplayer menu, a feature called Uncharted TV which also shows recent media from Naughty Dog, gameplay of Uncharted 3 multiplayer, and user created content.
Allows updates, 90 second match highlight videos, screen shots, and invites to be sent, shared, and received via Facebook from inside the game. According to Naughty Dog co-president Christophe Balestra, "Our goal for Facebook is to really make sure you can interact with your Facebook friends the way you interact with your PSN friends. You can talk to them (and) you can invite them to your party. You are going to see icons of people’s faces and their real names. So right away it is going to feel bigger." This Facebook interaction can lead to the player receiving in-game "gifts."
PatchesNaughty Dog have been active post-release by rolling out updates and improvements via patches.
Uncharted 3 multiplayer became available to download for free on February 26, 2013. F2P players can play up until Level 15, but after that they will no longer unlock anything nor earn money. Features such as split-screen, higher level caps and co-op must be bought in the store to be played.
On the 5th of June, 2019, Naughty Dog announced that the servers for Uncharted 2, Uncharted 3 and The Last of Us (PS3) would be getting shut down on September 3rd, 2019. Because of this, new DLC bundles were added to the PlayStation Store which included all DLCs for the three games for free.
