Strategy and Mechanics Breakdown
Utilizing Mettaton NEO's Leader Buff
Range is the most critical attribute for clearing Neutral Corridor Act 1 because of the map's corridor structure. Mettaton NEO's leader skill specifically enhances units belonging to the CORE category that possess an explosive secondary typing.
When active, this skill provides:
- +50% Range: Allows units to cover massive stretches of the hall before enemies advance.
- +25% Telegraph Size: Increases the area affected by unit attacks.
- Negative SBA: Lowers seconds between attacks, improving overall attack speed and DPS uptime.
- Crit Buff: Further augments overall team damage.
Knight Knight fits this leader profile directly, serving as the primary heavy-hitting damage dealer to burn through enemy waves.
Countering Bosses and Leak Management
Sans serves as the primary obstacle in this stage. Player testing highlights the following tactical roles:
- Woshua's Soak: Deploy Woshua to inflict soak on Sans. Existing run footage confirms that soaking Sans is an essential step to bringing him down reliably.
- Muffet's Clean-Up: Despite heavy range damage from Knight Knight, fast-moving enemies or tough targets can push through your primary choke point. Muffet's bone-channeling attacks catch stragglers in the back so they do not breach your base.
- Economy Scaling: Place your money units early to build sufficient cash flow. High-tier upgrades on your DPS units are necessary to sustain damage against incoming waves.
Exact enemy wave counts, enemy health pools, and precise tile placement coordinates are not detailed in official documentation or available run footage. Players should adjust placement along the center track to maximize Mettaton NEO's range buff.
