Enemy: Tempest of Violence is an action-adventure game with a sci-fi setting for the Commodore Amiga, released in 1997 under the label Anachronia. The game was developed by André Wüthrich and Michael Tschögl with technical support from Thomas Schneider.

The player has to find and rescue as many civilians as possible from different spaceships in a limited time per level. While doing so, they must avoid enemy aliens and use a variety of weapons to shoot their way through the various spaceships. Enemy: Tempest of Violence has an intricate story that is told between levels. An interesting part of the story revolves around befriending some aliens, which breaks the common narrative that humans are good and aliens are bad.

A sequel called Enemy 2: Missing in Action was released in 2013. The sequel featured thirty new levels, a continuation of the story, new puzzles, and non-linear gameplay, adding up to around eight hours of gameplay.

In 2022, André Wüthrich released an anniversary edition of Enemy: Tempest of Violence, which is not a sequel but an optimisation of the original game.

The games were designed to run on all Amiga models from Kickstart 1.2 onwards and require at least 1 MB of RAM. Today the games are available for free download in English and German, including the manuals.
