Flechette Grenade

The Flechette Grenade is one of Marathon's most unusual pieces of equipment: it launches a burst of seeking projectiles that home in on nearby targets and, uniquely, heal the thrower on each hit. This dual-function mechanic makes it part offensive denial tool and part sustain option, rewarding aggressive players who deploy it while already pressing an engagement. The seeking nature of the flechettes means they can catch enemies peeking around corners or retreating behind cover, giving the grenade a deceptive effective range.

Beyond direct combat, the Flechette Grenade works as area denial by guarding a chokepoint and simultaneously revealing enemy positions as projectiles track toward them. Its healing-on-hit synergy is particularly strong on runners who lack passive regeneration or sustain abilities, offering a way to recover health during the chaos of a firefight. Classified as B-tier equipment, it rewards players willing to learn its unconventional mechanics and is worth carrying as a situational alternative to pure damage grenades.
