Ambush game mode

Ambush is an event game mode, meaning it's only available through the events screen. Ambush duels will be made available regularly through the events screen, but will generally come with a fixed difficulty level and setup.

In an ambush game, players will face a single, computer controlled opponent. This opponent will have a regular, single-race, randomly generated deck. What makes ambush different from regular Single Duel games, is that the opponent will start with several ships already in play. The opponent will go first in each game, but in their first turn, they will only launch a number ships. From that point onwards, the game will have a normal setup, and players will be the first to have proper full turn.

Ambush opponents currently always have decks and starting ships made up out of a single race. Since the opponent doesn't have to spend energy to play its set of starting ships, those ships can be dual color, but their major race will be the same as that of the opponent's deck.
The number and general size or powerlevel (as controlled by their shipclass) of the starting ships is controlled by the difficulty level of the opponent. The difficulty also affects the make up of the opponent's deck and base, similar to how it works for Single Duel games. The only difference is that the opponent will not get combat boosts at higher difficulty levels.
The opponent will generally start out with fewer cards (5) in their opening hand by default. The number of cards will go down even further (3) based on the difficulty level or for specific ambush submodes.

Ambush comes in different submodes, which further influence the kind of cards the opponent starts with or will have in their deck. Ambush duels will come with a guaranteed reward for the first time a player defeats the opponent. For more information regarding the kind of rewards ambush can offer, refer to the droprates article.


Ambush : the default ambush submode. Available for the 8 main races, in difficulty levels ranging from 60 to 130 (in steps of 10). The opponent will start out with several regular ships.

Mercenary ambush : Available for the 8 main races, in difficulty levels ranging from 30 to 100 (in steps of 10). The starting ships will all be mercenary cards (without upgrades). The deck of the opponent is still a regular generated deck.


Ambush games can currently only be started from the events screen. Players will need to be connected to the internet before they can access the events screen. Having an account, or being logged in is not required.

Ambush games are generated by a server. In the current setup, one regular ambush and one mercenary ambush game will be created each day. Each game is available for 24 hours. The events screen will list for how much longer an ambush game will be available.

Starting cards

The number and general powerlevel (as controlled by the shipclass) of ships depends on the difficulty level of the duel.
Shipclasses are divided in several groups (A, B, C, D, E, F), which in turn will be present a number of times based on difficulty level, as shown in the table below.
A : fighters, B : fighters, supports, science ships, industrials, C : cruisers, D : destroyers, carriers, E : battleships, titans, F : any.

0-9 2 0 0 0 0 0
10-19 0 2 0 0 0 0

Group F (any shipclass) is not present by default, but will be used in case a certain race doesn't have a ship in a certain subclass.
The location of the chosen ships on the field is always symmetrical. Uneven numbers of ships will take up the central slots with the smallest group on the outskirts of the formation. Even numbers of ships will always leave open the central ship slot.

For regular ambush the chosen cards are not further modified and will simply enter play in the opponent's first turn. For mercenary ambush, the chosen cards are replaced by their mercenary variants (without any upgrades).
