Two upgrade tracks
A tower can level up inside a match, and it can also level up in the lobby inventory. Match levels spend the coins you earn that round and raise damage, fire rate, or income. Lobby levels spend coins you kept and raise the tower you bring next time. The Collector! is the badge for unlocking every tower. The Final Boss is the badge for maxing every tower and every pet.
Match upgrades change the model through color tiers. Reports name red, blue, pink, and diamond. A Crossbow at level 6 has been seen in the red tier. Cannons have been pushed to pink and diamond on long runs.
What each tower is for
| Tower | Use it for | Watch out |
|---|---|---|
| Crossbow | Starter single-target. Cheap enough to stack. | Door tier locks the higher levels. |
| Cannon | Chunk damage from early through mid waves. A free Cannon crate has been claimed from the shop. | Still needs the door gate for top tiers. |
| Flamethrower | High damage in a short range at the doorway. | Enemies outside that range are not its job. |
| Mortar | Boss health. Set targeting to Strongest. | Crate unlock, not a starter. |
| Turret | Steady shots, with a target toggle. | Often replaced by Mortars or high Cannons on Hard. |
| Medical Base | Heals the door if the door is inside the beam. | It does not shoot. |
| Tesla | Named as a coin defense for longer runs. | Damage, range, and cost are not published. |
Lobby path
- Clear matches and pick up crates from Lorenzo.
- Open the inventory and spend coins on the towers you actually equip.
- Stay inside four loadout slots unless you buy the 5th Slot pass for 99 Robux. That slot can be a tower or a pet.
- The VIP pass is 399 Robux. It adds interior build space, a permanent 2x speed toggle, and a username tag. It does not replace door upgrades.
Duplicate crate pulls raise a tower toward its level cap. There is no public table of the max level for each unit. The Final Boss badge is the completion check.
