Alien Mobilization List/Strongbox

## Overview

Similar to the event Incursion, various Alien fleets spawn in convoys from Unstable Wormholes. They automatically attack nearby player fleets within 10 levels, so beware!

Defeating these fleets gives you event points which you can use to redeem Bronze, Silver, Gold and Legendary prize boxes, which contain Reusable Items or even blank hulls! Clicking on a link in the prize list for a strongbox will redirect you to a page detailing its contents.

With the introduction of the Xeno Division, Strongbox-based Alien Mobilizations have been replaced by a newer version of Alien Mobilization. Here is a list of past Strongbox-based Alien Mobilizations:
