In an update in 2012, this upgrade was reworked into the tier 4 upgrade High Energy Beacon, which still reduces Activated Ability cooldowns, but also adds a laser attack and is more expensive. The previous tier 4 upgrade, Monkey Town, was moved into Energy Beacon's tier. Despite being reworked, in the mobile and console versions, High Energy Beacon is still named "Energy Beacon".
