Biomes
The hordes of rogue agricultural drones are spreading to other colonies, and you can now defend homesteads in three different biomes in Day Mode. These "biomes" are just different color-schemes that provide players with options beyond the desert region.
(Super) Bonus Attacks
Each tier 6 turret now has a small chance upon firing to trigger a Super Bonus that will double their fire rate and range for a limited time. The 10% regular bonus attacks still exist and can trigger during these Super Bonus activations.
