Patch notes discussion April 2025

[BIGNEWY]

DCS 2.9.15.9408

Introduced a new terrain module: DCS: Cold War Germany by Ugra Media

Introduced a new campaign: DCS: F-4E Red Flag 81-2 Campaign

DCS: Data Transfer Cartridge (DTC) by Eagle Dynamics

This initial release of the DTC will allow you to create custom countermeasure programs and radio communication presets for the DCS: F/A-18C and DCS: F-16C. In future updates, this will be expanded to include more mission planning data like navigation waypoints, targets, threats, datalinks, route points, weapon settings, and more. The functionality will also be extended to other aircraft such as DCS: AH-64D and DCS: A-10C II Tank Killer.

DTC programs can be created in the Mission Editor and prior to flying a single-player or multiplayer mission from the Briefing Screen. DTC programs can be saved, exported, and imported, allowing you to create multiple DTC programs for each aircraft based on the mission, and allow you to share DTC programs with friends.

Please see the DTC Guide here and the instructional video.

I had the same, seemed to recognise i'd bought the map at about the 3rd attempt.

[Boosterdog]

@BIGNEWY am I correct in assuming the Cold War has generated the type of server crashing chaos normally reserved for day 1 Nvidia cards?   Its not showing anywhere, the authoriation is faulting, the game cant update my module data and its all genrally very circle of doom.  

 

 

[BIGNEWY]

server is under heavy load so please be patient with the site, everyone is trying to buy at the same time.

Yeah while it is annoying for the server to be struggling it shows how popular and anticipated the patch and terrain is.

Im curious if the new ground vehicles showed in the launch trailer will be in the sim? they werent in the patch notes. Pretty sure I spotted a T-62 and BTR-60, and we dont have those

They're almost certainly scenery objects baked into the map.

Scenery objects can be animated (see wind turbines etc).

EDIT: Actually, with the video - those could very well be new assets.
