+[Theta Wave] is an open-source space shooter game by developers [@micah_tigley] and
+[@carlosupina]. It is one of the showcase games for the [Amethyst Engine]. In
+the past month, the ["Loot"] update was released which enhanced how loot drops
+are rolled, spawned, and how their effects are applied to the game. The Loot update
+also added an attraction system which allows for entities to repel or attract
+other entities.
+
+Now an ["Organization"] update is in progress for Theta Wave. This update will
+divide Theta Wave into two workspaces, a library and a binary. This update will also
+add documentation comments for all of the library's features.
