The conversion process of this sub strain have been skewed in favor of heightening the creatures aggressiveness. This had the added effect of removing any form of self-preservation instinct. As such, the Hardfangs are often seen rushing into combat where they make use of their Arc Charger.
Royal Marine Commandos often make use of designated marksmen rifles and sniper rifles to eliminate the Hardfangs before they can get close enough to become a threat.
- Hardfangs rarely use cover, and will commonly charge straight for the player, so they're pretty easy to kill. The player must be wary of their Arc Chargers, as these can do serious damage to the player's health.
- Hide in a corner or enclosed space, wait for them to come to the player, then greet them with a Rossmore 236 blast.
- Using the Fareye and slow down time is also an efficient way of killing them before they can get close enough to damage the player.
- Their Arc Chargers will render Backlash Grenades completely ineffective.
