September 2026 update: mo.co has gone back to beta and the live game is on low maintenance. The team confirmed no new weapons in the upcoming seasons, so the Season 4 roster is still the current meta and this guide stays valid. Cosmetics and Collector Levels are safe; Weapons, Cores and Career Level progress is still under review.
Understanding Weapon Tiers in MO.CO (Season 4)
In mo.co, your weapon choice can make or break your hunting experience. Season 4 added Pyro, Storm Weaver and Medicine Ball, and the relaunch reshuffled the rest of the pool, so the ranking below reflects the current meta rather than the launch one. This guide ranks every weapon from S tier (exceptional) down to D tier (outclassed), so you can pick with your eyes open.
This ranking mirrors our interactive tier list, where you can drag every weapon into your own order.
S-Tier Weapons: The Elite
These weapons consistently outperform in most situations:
Speedshot
- Best single-target damage dealer
- Excels in boss fights
- Weakness against groups can be covered with gadgets
A-Tier Weapons: Strong Picks
Consistently good, a step below the top three:
- Techno Fists: The easiest weapon to be effective with, strong team buffs
- Singularity: Black Hole grouping plus a healing pulse
- Hornbow: Reliable ranged damage with strong single-target pressure
- Pyro: Best pack clear in the game, but overheating stuns you too
- Blood Sucker: Vampiric melee that sustains itself, punishing to misplay
- Zapsicle: Chain lightning that stuns whole packs at once
B-Tier Weapons: Situational Picks
Effective with the right build, or in the right hands:
- Venom Bow: Poison damage over time, strong against big health pools
- Staff of Good Vibes: Dedicated team healing, best in coordinated groups
- Wolf Stick: The wolf taunts and tanks while you deal damage
- Fancy Wrench: Turret engineer, great sustained damage from safety
- Toothpick and Shield: Tank-focused with heavy damage reduction
C-Tier Weapons: Falling Behind
Playable, but you are working harder than you need to:
- Monster Slugger: Fine AOE, but outclassed by every S tier melee
- Medicine Ball: Immune System is excellent, everything around it is slow
- Buzz Kill: The bees are fun, the damage does not keep up
- Portable Portal: Build-dependent and no longer part of the NEO rotation
D-Tier Weapons: Skip These
- CPU Bomb: Big burst on paper, too slow and clunky to land in current content
