Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for DEFCON 1: Deep Dive is 90–180 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists DEFCON 1: Deep Dive for ages 14 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
DEFCON 1: Deep Dive has a complexity rating of 3.5 out of 5 from BoardGameGeek players, which makes it a medium-weight game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
DEFCON 1: Deep Dive belongs to these categories: Wargame, Political, and Expansion for Base-game. Its main mechanics are Variable Player Powers. Categories describe the theme and setting of a game, while mechanics describe what players actually do on their turns. Each mechanic links to a catalogue hub with similar games, which helps when you want something comparable.
The credited designers of DEFCON 1: Deep Dive are: Florian Dumont.

The catalogue lists DEFCON 1: Deep Dive as an expansion for DEFCON 1.
