It is best used with players who regularly use a hardsuit. To activate battle mode, hold C while in the suit/tank for about a second. It cannot be disabled once turned on, forcing players to wait the full 40 seconds for it to recharge.
Hardsuit Battle Mode will only reduce damage taken but a skilled opponent with the RL5 Armor Stinger can still destroy a hardsuit. When Hardsuit Battle Mode and an enemy players uses the FT18 Flamethrower no damage will be dealt to the hardsuit.
Note: Need additional testing to see if the damage-over-time from the FT18 Flamethrower is dealt once the Hardsuit Battle Mode deactivates.
Use while inside a Hardsuit for 10 seconds of reduced damage, protection from flames and protection for the suit's weak point.
