New mode All-Out War: your full squad vs. hordes

Each battle lasts 5 minutes, and a big boss joins the attack when 2 minutes remain. Hordes pour in from every side, and fallen squad members stay down until the battle ends. Every week the scenery, weather, enemies and big boss change, and your score earns weekly rewards (Gems and Squad Medals). The new All-Out War mode unlocks after you clear Stage 10 and is played from the stage list.
