Just as we expected from the teaser last week, Ubisoft has officially announced the Ghost Recon Wildlands Splinter Cell crossover with a special mission! Sam Fisher will be joining the third-person shooter game in Special Operation I, and yes, it’ll be free.

The crossover event will be available to everyone tomorrow, April 10, on PS4, Xbox One, and PC, with Splinter Cell protagonist Sam Fisher once again being voiced by Michael Ironside. Watch the reveal trailer below and get your goggles ready!

Starting April 10, a wealth of exclusive Tom Clancy’s Splinter Cell^® content will be introduced to the Tom Clancy’s Ghost Recon^®Wildlands main game and Ghost War PvP mode, including a new PvE mission, exclusive customization items and a new Ghost War PvP class. Players* will be able to play alongside Sam Fisher, the iconic character from the critically acclaimed Tom Clancy’s Splinter Cell^®espionage series, and help him complete his new high-risk infiltration mission in fictionalized future Bolivia. This new special challenge is playable solo or with up to four players in co-op and is one of the most difficult missions the Ghosts have ever faced. The nighttime stealth mission will require players to use all the tools at their disposal to succeed.

Special Operation I will also bring the Echelon, a new assault class available in all PvP modes that will expand the Ghost War roster to 18 unique classes. The Echelon is a part of Sam Fisher’s Fourth Echelon team, and therefore has access to high-tech equipment as well as the Sonar Pulse ability that allows him to see enemies behind walls at short range and gain tactical advantage over the opposing team. Ghost War players will be able to get early-access to the new class by using their Prestige points or with the Year 2 Pass.

While the Ghost Recon Wildlands Splinter Cell mission will be available permanently, the rewards for completing the mission (Sam Fisher’s iconic sonar goggles with a new night-vision filter & more), will only be accessible until this Special Challenge ends on May 16. In addition to the challenge, players can customize and arm their Ghosts with the Splinter Cell Gear Pack, which includes new customization items and weapons such as the Karambit Knife, and a fully customizable SC 4000 prototype Splinter Cell assault rifle.

Once the Splinter Cell content is out tomorrow, we’ll be sure to let people know. Let’s hope this is a precursor to a full-fledged Splinter Cell game that’ll be announced at this year’s E3.
