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.


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


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


  • Does no 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.
