Fragile Alliance provides the groundwork for a few of the other multiplayer modes in Dog Days
, but each mode adds a single twist that fundamentally changes the way the game is played.
For instance, Undercover Cop turns a random team member into a mole who must destroy the Alliance before reaching the escape point. If he meshes completely with his new buddies, his cover will be blown when the cops don't open fire.
Finally, Arcade Mode is a single-player variant on Fragile Alliance.
