These are a range of additional objectives that players try to achieve for additional Victory Points. The twist is that not all Secret objectives are achievable by every army or in every game, and that with each passing round the players must choose a single objective from a diminishing pool:
When writing their muster lists) for a matched play event at which Secret objectives are in use, each player must choose and list six Secret objectives from the 12 listed below.
At the start of each game, each player must choose one of their Secret objectives and make a note of it on a piece of paper which should then be placed face-down at the edge of the battlefield, in sight of their opponent.
At the end of the game, when calculating Victory Points, both players reveal their Secret objective. If either has achieved their objective, they win a VP bonus as stated in the Secret objective's description.
After each round, when submitting results to the scorekeeper, each player must also record which Secret objective they chose for that round, and whether they were successful in achieving it.
Once a Secret objective has been selected, it cannot be selected again for the remainder of the event.
