Last week Ubisoft revealed Splinter Cell’s Sam Fisher was returning as part of Ghost Recon Wildlands’ upcoming Special Operation 1 update, and now we have a new trailer showing the gravelly-voiced killer in action. Unsurprisingly, the trailer includes a lot of darkness, sneakiness, and death – check it out, below.

　　The Special Operation 1 update includes the new campaign mission The Call, in which Sam Fisher (once again voiced by Michael Ironside) travels to Bolivia to stop a rogue CIA agent from selling military secrets to the cartels. The update also includes a bunch of Splinter-Cell-themed weapons and goodies, the Sabotage PvP mode, which comes with five new maps, AI teammate customization, and more.

　　Here are the full patch notes for the update:

　　New Content: Campaign

　　Splinter Cell Special Challenge

　　The free Splinter Cell Special Challenge will be available for all players for one month, starting on April 10th. The rewards for completing this mission are Sam Fisher’s Night Vision Goggles with their own Splinter Cell vision, new Proximity Mines and a Splinter Cell Patch. The mission will still be accessible after the challenge is over, but the rewards will no longer be available. The mission starts in La Cruz.

　　AI Teammate Customization

　　In our Campaign Mode, AI Teammates outfits can now be customized via the Charactersmith menu. Please note that the gender, face and weapons cannot be customized via Charactersmith.

　　New Content: Ghost War

　　Sabotage

　　In Sabotage, teams take turns in defending or attacking two radio transmitters. The attackers must activate one radio transmission and defend it until it finishes, while the defenders must either stop the transmission or prevent the activation in the first place.

　　Maps

　　The Sabotage game mode comes with 5 new maps: Library, Zinc Mine, Unidad F.O.B., Trainyard, and Rocha. They are all available for both Quickplay and Ranked modes.

　　Classes

　　Echelon: The Echelon Class is equipped with Ultra High Frequency Sonar Goggles, standard equipment to Fourth Echelon agents. When activated, it sends sonar pulses that reveal enemy players in his vicinity for a short time. This allows the Echelon to gain tactical advantage over its enemies, especially when used under low-visibility situations like nighttime or inside smoke clouds. Also, the ability's range is greatly reduced while moving, so keep still for maximum effect. The Echelon also comes equipped with the brand-new proximity mines.

　　Medic: We have replaced the Medic's mines with flashbangs.

　　Tech: We have replaced the Tech's C4 with proximity mines.

　　Pointman: We have reduced the damage output of his ACR and AK-12 by small amounts to bring them to a similar level and balance the class.

　　Perks

　　We've introduced one new Marksman perk called Hollow Point Ammo.

　　Hollow Point Ammo: The Hollow Point Ammo perk applies bleeding damage over time, for 90 seconds, with every bullet hit. If the enemy is already affected by it, every bullet that hits will refresh the duration. Additionally, while the effect is active, Battle Rage and Adrenaline Rush will not regenerate health. Interacting with a supply crate will remove the bleeding effect.

　　Ranked

　　Rating Decay: We've introduced Rating Decay which applies when players are not participating in Ranked matches for a set amount of time. The decay makes a player's rating go down on a daily basis which often leads to rank demotion, though it stops applying for players that are Silver or Bronze. To prevent this from happening, players must be active in Ranked matches on a regular basis.

　　Rewards: We've increased the amount of Prestige Credits that are awarded at the end of the season.

　　Other Improvements

　　Proximity Mine: We've introduced a new type of explosive device, the Proximity Mine. Similar to the C4, it can be attached to walls and other surfaces, and detonates when detecting an enemy in proximity. It cannot be defused and the damage it deals is lower than a regular mine.

　　Tutorials: The Tutorials page has been re-worked for better visibility and quicker navigation between pages of interest, removing the need to cycle between all pages to reach a certain tutorial.

　　If you really need the lowdown on every tweak and bug fix included in the update, you can get that, right here.

　　Special Operation 1 is included Ghost Recon Wildlands’ $30 Year 2 Digital Pass, which includes all four updates, an exclusive customization pack, four Special Ops battle crates, four Ghost War battle crates, and early access to all the new Ghost War classes.

　　Ghost Recon Wildlands is available on PC, Xbox One, and PS4. The Special Operation 1 update hits tomorrow (April 10th), and there's also a free weekend from April 12th to 15th on all platforms.
