Phantom Kill is a local multiplayer game for up to four players.
In this game, the players can neither see their own characters, nor the other players' characters. They can, however, see the position of the players from 1.5 seconds ago. Players have to guess and predict, where all players are, based on their ghosts.
Only by attacking is the player made visible for a short amount of time, making it a trade-off between being able to hit another player and giving away your own position - thereby running the risk of getting hit themselves.
The goal of the game is to get the most kills in one game, where every player has 5 lives.
