Objectives

From Exterminatus Manual

Each Exterminatus map has a series of objectives in it. Each team starts with it's own objective. Dead players are spawned at the objective owned by their team and watch the view from their team's next objective while waiting for a spawn wave.

You can capture objectives which will reward you with a better class next time you respawn. When an objective is captured the capturing team will begin to spawn there and a new next objective is set. Listen out for the drum roll that indicates an objective has been captured.

When all objectives are captured by one team the game will end when the last member of the enemy team is killed.

HUD Symbols

Each objective is marked on the players HUD (heads up display) with a symbol. Objectives held by the imperial team are marked with a white imperial eagle. Objectives held by the tyranid team are marked with a red tyranid creature. Neutral objectives belonging to neither team are marked with a haze. These objective symbols can be seen though walls to help you find your way to the action in un-familiar maps.
