A class-based shooter testing approachable aim and counter-picking against human teams.

Reversal-timing wrestling that becomes a prediction game against humans.

Plants vs. Zombies: Garden Warfare
Human opponents flank and juke in class-based skirmishes
WWE SmackDown! Shut Your Mouth
Versus friends, reversal baiting becomes a prediction game
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Plants vs. Zombies: Garden Warfare
Sticker pack unlocks randomise progression, not matches
WWE SmackDown! Shut Your Mouth
Mild AI and momentum randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Plants vs. Zombies: Garden Warfare
Class counters and objective timing reward team planning
WWE SmackDown! Shut Your Mouth
