Zombie Titans Tier List
S-A-B rankings for Bulldog, Volt, Mammoth, and Mantis across real siege roles.
This Zombie Titans tier list ranks all four playable mech Titans - Bulldog, Volt, Mammoth, and Mantis - for the jobs that actually decide whether your eight-player wall survives. OMG - One More Games launched the free-to-play experience around 13 October 2026. The core loop is unforgiving: pilot a Titan, hold through March -> Surge -> Behemoth, and delete flying Screechers, Gasbags, and Carriers before they crack the line. Scrap invested in the wrong frame hurts more than a missed daily supply drop.
We score each Titan on four criteria, then merge into a simple S / A / B band. Full per-Titan notes, ability reminders, and matchup tips live on Titan Rankings. Build-oriented loadouts continue on Titan Builds. Behemoth-specific execution is covered in Beat Behemoth.
Ranking criteria
| Criterion | What we measure |
|---|---|
| Wall hold | Consistency clearing ground swarms during March and early Surge without overheating into a wipe |
| Behemoth DPS | Burst and sustained damage during the named boss phase |
| Flyer clear | Tools against Screechers, Gasbags, and Carriers |
| Beginner | Forgiveness for new pilots still learning cockpit view toggle and ability cadence |
Meta shifts after balance patches - recheck Updates when OMG tunes overheat, scrap economy, or boss HP.
Current overall tiers (November 2026)
S tier - first Scrap priority
Volt - Chain-lightning arc gun, lightning strikes, Tesla field, and EMP pulse give Volt unmatched flyer clear and strong multi-target value in Surge. When Carriers and Gasbags stack, Volt’s kit answers the sky while still contributing to Behemoth windows. Beginners benefit from forgiving splash; veterans abuse EMP timing. If you only fully upgrade one Titan early, Volt is the safest S-tier Hangar bet.
Mammoth - Siege cannon, mortar barrages, carpet bombs, and siege ram scream Behemoth DPS and structure-breaking pressure. Mammoth anchors coordinated lobbies that already have someone on flyer duty. Slightly less beginner-friendly if you ignore the sky, but S-tier whenever the wall’s problem is raw boss HP.
A tier - excellent specialists
Bulldog - Twin gatlings, rocket pods, swarm missiles, and ground slam. Premier wall hold and March cleanup. Swarm missiles punish packed zombies; ground slam resets melee pressure. Flyer tools exist but do not match Volt’s chain lightning. Ideal first Titan for players who want simple aim and reliable Scrap farming on ground waves.
B tier - high skill, situational
Mantis - Twin scythes, blade dashes, leap strikes, and berserk. Explosive melee mobility and berserk uptime can melt elites in the right hands, but missing dashes near the wall is punishing for beginners. Flyer clear is weaker than Volt; Behemoth DPS depends on uptime. Climb Mantis after you own cockpit movement and have a squad covering sky threats.
Role snapshot table
| Titan | Wall hold | Behemoth DPS | Flyer clear | Beginner |
|---|---|---|---|---|
| Volt | A | A | S | S |
| Mammoth | A | S | B | A |
| Bulldog | S | B | B | A |
| Mantis | B | A | C | B |
Overall bands: Volt and Mammoth = S, Bulldog = A, Mantis = B for general queue play. Duos that lock Volt + Mammoth cover sky and boss in one draft.
How to use this list in the Hangar
- Claim the OMG group 1,000 Scrap bonus and daily supply drop - see Codes Hub for promo status.
- Unlock and upgrade Volt or Bulldog first depending on whether flyers or ground swarms kill your lobbies.
- Add Mammoth before pushing difficult Behemoth clears.
- Treat Mantis as a flex / mechanical challenge once Scrap is comfortable.
- Read Titan Rankings before respec-style spending mistakes.
Party composition tips
On a full eight-player server you rarely need four Mammoths. Aim for:
- At least one Volt (or equivalent flyer focus) every Surge
- At least one Mammoth when Behemoth HP feels spongy
- Bulldogs to stabilize March and protect repair windows
- Mantis only when the pilot can stay alive through berserk
Solo or thin lobbies should bias Volt/Bulldog over pure Mantis greed.

Tier lists are tools, not scripture. A practiced Mantis that never overheats into a wipe beats an idle Mammoth. Still, when Scrap is scarce after launch, follow S-tier priorities, cover flyers, and keep the wall upright through every Behemoth roar.
Frequently Asked Questions
Quick answers for Zombie Titans pilots.
Who is the best Titan for beginners?
Volt ranks highest for beginners thanks to chain-lightning forgiveness and strong flyer clear. Bulldog is a close second for simple ground hold.
Which Titan is best for Behemoth?
Mammoth leads Behemoth DPS with siege cannon, mortars, carpet bombs, and siege ram. Pair with a Volt for sky control.
How often will this tier list change?
After major OMG balance patches or enemy retunes. Recheck the Updates Hub and the detailed Titan Rankings page.
Is Mantis bad?
No - Mantis is B-tier for general queues because it is mechanically demanding and weaker into flyers. Skilled pilots still shred with berserk uptime.
