AMPs system is part of the WildStar Action Set builder. While leveling players get AMP points, which can be used for unlocking AMPs. Tier 1 AMPs are unlocked by default, when you collect enough AMP points, but AMPS Tier 2 and Tier 3 are locked, and players have to unlock AMPs with corresponding AMP items first. These items can be obtained as quest rewards, random world drops, from Scavenged Supplies boxes you get from Challenges, or you can buy them from vendors.
In the table below you can find locations for all Engineer Amps, for both factions Exile and Dominion. By clicking on the links in the Vendor columns you can see map location for each vendor. You can also search the table by choosing vendor name, or location from drop down menus at the top of the table.
