There are over 50 units in 8 Bit Tower Defense, including limited-event units, but the meta mostly relies on the Mythic and Legendary banner units and a few farm options. This guide will provide you with a tier list of the best meta units in this Roblox game, including their main features.

| # | Units |
|---|---|
| S | Headless Horseman, King Slime, Grim Reaper, Ember Phoenix, Boulder Turtle, Penguin |
| A | Quill Porcupine, Lucky Cat, Widow Empress, Spider |
| B | Firefly, Gunboy, Dragonfly, Beetle |

S-Tier Units
| Units | Features |
|---|---|
| Headless Horseman | This Halloween Event unit has Jack’s Curse, which hits every enemy with a curse for 6 seconds, and when a cursed enemy dies, it explodes into burning pumpkin shards that deal 80% of the unit’s damage to all nearby targets. It’s also completely immune to stun damage from bosses, and its Split Head upgrade splits its head into three flaming projectiles that bounce between up to 5–6 enemies each, inflicting heavy burn damage. |
| King Slime | Summons massive slimes with a huge HP pool that march down the entire track and wipe out all enemies and bosses they encounter. Note that slimes scale up in size, gain extra resistance, and do not disappear that quickly, making this unit incredible for farming and clearing stages. |
| Grim Reaper | This is the top Mythic unit that sits at the highest shelf of the summon banners and can be evolved into an even stronger form. It is an executioner type unit with the one-shot kill potential that also hits air enemies. |
| Ember Phoenix | Here’s another Mythic banner summon that may deal fire damage, have flying and revive abilities. Just like Hollow Night, this powerful unit can be evolved into an even more powerful form. |
| Boulder Turtle | Possesses massive AoE range of up to 157+ and deals splash damage, which is capable of trapping enemies right at their spawn area. Its upgrades unlock devastating moves like “Meteor Rain Down,” although its single-target damage is not as high. |
| Penguin | Launches giant snowballs that completely freeze groups of enemies, causing frozen targets to take extra damage from all other units. It also deals a belly attack that hits everything along a stretch of the path and scales massively with upgrades for up to 70% extra damage and faster attacks. |
A-Tier Units
| Units | Features |
|---|---|
| Quill Porcupine | High early-to-midgame damage dealer with 13 base DPS and a huge range between 81 and 100, which allows it to easily carry early waves when spammed. Its quills inflict bleed damage worth 10% of hit power, and later upgrades unlock piercing damage with Quill Burst. |
| Lucky Cat | Essential economy unit that generates extra cash at the end of every wave, specifically 400 per wave when leveled. This farming unit can also attack enemies by flicking gold coins that ricochet on jackpots. |
| Widow Empress | Here’s one of the less powerful Mythic banner units, which is capable of stacking its venom. You can use it for her Keen Eye passive that increases her range by 25%. |
| Spider | Affordable unit that costs only 450 cash with crowd control skills that shoots silk and leaves webs on the track to slow down enemies. It’s also capable of hitting flying enemies, making it a reliable support unit. |
B-Tier Units
| Units | Features |
|---|---|
| Firefly | This is a solid early DPS that shoots sparks, which bounce between up to 4 enemies and deal triple damage to flying units, making it a great anti-air summon. Though it is a bit expensive, and its late-game upgrade costs 2,900 cash with a smaller range compared to other ranged specialists. |
| Gunboy | Reliable early-game damage dealer that’s capable of holding down early waves with minimal support. Outscaled by higher-rarity units in mid-to-late stages of the game. |
| Dragonfly | Deals very fast attacks, but is viable only in the early game as a starter unit, though it can hit aerial enemies. Its low base damage of around 2.0–2.2 and small range quickly fall off in usefulness as armored enemies start appearing in waves. |
| Beetle | Very cheap to deploy for only 250 cash, rolling up to attack and knock over nearby enemies, providing useful early stuns. But it has an extremely small attack range, making it ineffective unless you place it right on top of a tight corner or a choke point. |
The rest of the units in the C-tier are free starter units with generous placement limits and decent early range, but low damage and slow attack speed will prompt you to quickly replace them as soon as you summon Rare or Legendary units.
