My game is a tower defense game that is inspired by the story of Destiny 2. Destiny 2 is an online-only multiplayer first-person shooter. My game uses some characters of their game, but also the incorporation of my own. The game takes place around the time of Destiny 2, when the enemies in that game (The Cabal) siege the city and eventually take over. In my game, the goal is to repel the Cabal and successfully waste out their troops and force them to retreat, leaving the Guardians (the protagonists) who are on post victorious.
