If you aren’t already planning on participating in the “The Lab” this weekend — or haven’t in previous weekends — log in to UNCHARTED 2 multiplayer and check out the limited-time-only “The Lab” playlist in competitive matchmaking.

This weekend’s episode of “The Lab” is Sniper Extermination. All players start with only Dragon Sniper rifles and there are no other weapons available on the map. The goal of the game is similar to our Elimination gametype — once you or your opponent has been dispatched, you’re out of the round until all opponents on either team are wiped out. The team with any or the most remaining players left alive wins that round. Best of five rounds wins the entire match. No Boosters are active for Sniper Extermination, so high-level players and teams who have unlocked Situational Awareness won’t be at an unfair advantage of those who haven’t unlocked Evasion yet.

We’ll be running Sniper Extermination on the following multiplayer maps:

• The Sanctuary
• The Train Wreck
• The Warzone The Plaza
• The Lost City

“The Lab” is open from Friday, June 25, at 10:00 AM PDT (what time is that in my city?) through Monday, June 28, at 10:00 AM PDT (what time is that in my city?).

You can stay up to date with future “The Lab” dates and gameplay parameters through this sticky post on the Naughty Dog community forums or by checking back on the “the lab” tag on the Naughty Dog blog. We will be posting the schedule for “The Lab” weekends for July early next week.

Hopefully very few of you are asking “What is The Lab?” If you are, head over to this post on NaughtyDog.com which gives you a bit more background on what to expect.

One more thing. Do us a favor and log in to UNCHARTED 2 multiplayer next weekend for a little something special. We’ll reveal next week what we’ve got in store for our multiplayer community.
