For instance, the current season is all-in on grenade launchers, which with the right mods unlocked can both stagger Unstoppable Champions and debuff them via an insanely strong mod called 'Breach And Clear' that also reloads all your stowed weapons. Though not the most exciting, these are intended to not-so-gently nudge players towards experimenting with loadouts they might otherwise not bother with. The stuff in the first couple of columns is always a smorgasbord of anti-champion mods, discounted ammo scavengers and weapon reloaders.
Arranged in a 5x5 grid, mods are unlocked by earning XP, with the options becoming spicier as you move from left to right.
