How to unlock the And Then There Were Ten achievement in Ben 10 - Definitive Guide
You must first unlock all of the aliens before you can get this trophy. The last alien you unlock is Stinkfly, at the beginning of The Canyon level. To upgrade your alien, you must collect alien boost points, which you obtain from killing enemies, completing bonus objectives during fights, and hitting pretty much everything else (boxes, light poles, cars, etc) in the stages. To use the alien boost points to upgrade your aliens, you must find an upgrade spot either in the level you are currently in or return to campground and use the one there.
Each alien has 3 upgrades you need to purchase for them. Here is a list of the upgrades for each alien and their prices:
