Obelisk

Obelisk is an Object that can boost alien spawn rate or spawn aliens every several minutes. The obelisk must be anchored and its green line must be at the top in front of the sky, this works in Planets and Spaces. When powered, Obelisk will appear neon green cylinder in the sky and will spawn Aliens every minute, whether it be 5-20 minutes.

Make sure you have Gyro Turrets to prepare to defend the Obelisk from Aliens and you should pair EnergyShield with an Obelisk to prevent Energy-based Turrets from accidentally shooting Obelisk.
