Now that the Arma 3 Contact expansion is out, owners finally get to play the "First Contact" singleplayer campaign. We’re definitely still interested to hear your feedback. If you encounter specific issues, please consider filing a Feedback Tracker ticket. Of course other playable content, meaning the Livonia multiplayer modes, can be discussed here as well. For general expansion feedback we prefer this thread.
While it may be hard to avoid spoilers entirely in this thread, try to use the spoiler widget to encompass plot points.
How to access the campaign?
The campaign can only be played using Contact's 'Total Conversion' mode. This mode makes changes to various parts of Arma 3 and is primarily intended for the campaign, not for regular sandbox usage nor multiplayer. Once in, you simply press PLAY.
There are several ways to launch Arma 3 in that mode:
In the Launcher: press the PLAY CONTACT button.
In the Launcher, open the DLC page, select and enable Contact, then press PLAY.
For advanced use cases, launch the game with -mod=Contact
