In SAS 4, all power-ups' costs are proportional to player's level, as of the February 11th, 2015 update. Before the update, High Roller was always $25,000 (then $125,000), Tank was $8,000 (then $40,000), and Killing Machine was $10,000 (then $50,000), with the price changes occurring once the player reached level 30. On the mobile version, the powerups retain the pre-update prices (HR $25k/$125k, Tank $8k/$40k, and KM $10k/$50k).

NOTE: Deep Freeze, Zombie Hunter, Reaper, and Heavy Ordnance have been removed around July 2014.
