Alien Overgrowth

Alien Overgrowth is a rare creature-spawn weather effect in Mewgenics that fills the battlefield with strange alien bramble patches, creating terrain hazards that are distinct from the standard Overgrowth weather's vegetation.

Unlike normal Tall Grass and thornbushes, alien bramble has unique visual design and potentially different mechanical properties. The exact interactions of alien bramble with elements like Fire (which normally ignites standard vegetation) are not fully documented as of early March 2026, so players encountering this weather for the first time should test interactions carefully rather than assuming standard vegetation rules apply.

Alien bramble patches create movement hazards that units must path around, similar to standard bramble but potentially with different damage values or status effects on contact. The patches reshape the battlefield by blocking certain routes and creating natural chokepoints.

Alien Overgrowth can appear in any biome and is classified as a rare weather. It is one of the less frequently encountered weather effects, and community documentation is still incomplete. If you encounter it, use the tactical view to identify all alien bramble tile locations before planning your movement.
