The MazHatter 0 class offers a powerful damage-dealing role with a focus on wide-area attacks. In SCP Tower Defense, this premium unit releases hazardous gas over a medium range, dealing consistent damage to all enemies within the affected zone.

With its large area of effect, MazHatter 0 is ideal for controlling groups of enemies, especially those resistant to standard bullets. Its high cost reflects its strength, making it a valuable asset for players looking to dominate key points on the map through sustained area damage.

A1: Viral Technician

• MazHatter A1 specializes in infecting enemies with a harmful pathogen, dealing damage over time. Has a short range

• This upgrade offers a unique combination of offensive and support capabilities, although its limited detection range and high cost of deployment require careful positioning and strategic planning.

A2: Contagion Operative

• MazHatter A2 enhances the pathogen attack by increasing both the attack speed and damage dealt over time. Its medium-range effect allows it to infect enemies from a safer distance while dealing stronger sustained damage.

• This upgrade improves offensive capabilities significantly, making it more effective at controlling waves of enemies. While it sacrifices some of the unique detection features of A1, its faster attacks and stronger pathogen effect make it a powerful choice for sustained area control.

A3: Blackout Carrier

• MazHatter A3 offers a very large vision range combined with a highly potent pathogen attack. It fires pathogen shots rapidly, dealing increased damage over time.

• Additionally, enemies infected by the pathogen explode upon death, spreading the infection to nearby units and causing chain reactions.

• This upgrade excels at crowd control and area denial, making it ideal for players who want to maximize damage output and control large groups of enemies with sustained, spreading infections.

B1: Fume Handler

• MazHatter B1 releases a toxic smoke over a medium-sized area, dealing continuous damage to all enemies caught within the cloud. It fires the smoke rapidly, maximizing its damage output over time.

• This upgrade excels at controlling enemy groups by applying sustained area damage, making it a strong choice for players who want to weaken waves and slow enemy advances through persistent environmental effects.

B2: Containment Leaker

• MazHatter B2 deals continuous damage in a small radius around itself using radioactive barrels, while its released toxic smoke inflicts increased damage over a larger area.

• This upgrade enhances both close-range defense and area denial capabilities, making it effective at weakening enemies both nearby and within the smoke cloud. It’s ideal for players seeking to maximize sustained damage in tight zones and control enemy movement through hazardous environments.

B3: Tactical Officer

• MazHatter B3 releases toxic gas that slowly drifts forward beyond its initial deployment area, continuing to move for a duration before dissipating. This gas deals continuous damage to all enemies it contacts along its extended path.

• Unlike standard area effects that vanish at the edge of their radius, this upgrade allows the gas to cover a larger effective distance over time, enhancing area control and forcing enemies to reposition or suffer sustained damage.

C1: Acidic Bombardier

• MazHatter C1 fires grenades at close range that explode on impact, dealing immediate damage and creating persistent acid pools. These pools slow down enemies standing in them while continuously dealing damage over time.

• Although it attacks infrequently, its combination of burst damage and crowd control makes it effective for disrupting enemy advances in tight areas.

C2: Pyro-Corrosive Agent

• MazHatter C2 enhances its acid pools by causing them to ignite enemies standing within, dealing continuous burn damage in addition to the base acid damage. These acid pools now inflict armored-type damage, making them effective against heavily armored foes.

• This upgrade strengthens both damage-over-time and anti-armor capabilities, ideal for controlling tough enemies and weakening their advance through sustained area effects.

C3: Mutation Cleanser

• MazHatter C3 gains a special ability with cooldown—a unique vial that, when thrown, neutralizes all anomalous abilities of enemies within its impact area. This effect behaves like an acid pool, dealing damage over time while suppressing enemy anomalies.

• It fires at medium range, combining offensive damage with powerful crowd control by disabling enemy special powers, making it invaluable against high-threat targets.
