In Insect Armageddon, the interact button (Xbox 360: , PS3: ) is used to perform actions on the environment.
In order of precedence, when the interact button is pressed it will:
- partially fill the ticker removal progress bar for each press,
- revive a teammate while being held down,
- plant explosives on an anthill while being held down,
- or activate the lander external communication unit while being held down.
The interact button is not available while the battle or tactical armor's special menus are open (the player is holding down the left trigger) because the face buttons are temporarily remapped to the actions available in the special menu interface. The button that is usually the interact button then uses the bugzapper (battle) or deploys the upgrade in the top button slot (tactical).
