The I3a Tactical Heavy Armor reduces all damage taken by 20%. It is always active as long as you have it in your inventory. It is the first item unlocked, at level 2.


  • Increases the resilience of any marine who elects to wear it
  • Passive effect that requires no management


  • Does no damage


Wearing additional layered graphene armor plates improves resistance to all forms of damage.


  • Heavy Armor can help characters with low health, such as Medics and Techs, who already have enough to manage, want to avoid on-use items, and could use some extra survivability.
  • It's also a decent choice for a character on point, who's bound to bear the brunt of the enemy's attacks.
  • It has great synergy with Sarge's health bonus.
