Description
The UFO, which stands for Unidentified Flying Object, was an enemy that only appeared in Area 51 as part of the Area 51 Event. It had a similar speed as the Lawnmower, but had more health. This meant that it was a difficult enemy to kill without preparation.
Appearance
The UFO was a grey metallic flying vehicle, resembling a flying saucer. It had a blue glow around the sides.
Strategy
- Units can collide with the UFO, as its hitbox is below the mesh.
- Being slow, it means that high damage towers, such as the Sentry and Outlaw, can be used to effectively kill the UFO.
- The Freezer and Pyromancer can be used to slow the UFO down. Interestingly, the Freezer's ice crystals appear directly below the UFO.
