Shroom War
Read full descriptionHide full description
Lead a colony of mushrooms into turn-based artillery battles, Worms-style, across a forest floor that digs and crumbles under every shot. Build a four-mushroom squad, read the wind, carve tunnels, lay walkways and play each species' signature ability at the right moment. Every mushroom has its own role, habitat, traits and way of fighting. TWO CAMPAIGNS, THREE SEASONS • The Descent of the Undergrowth: ten territories, ten bosses, down to the heart of the Roots. • The Lantern Vigil (Halloween) and the Night of Bells (Christmas): two seasonal campaigns that open with the calendar, each with its own maps, species, boss and music. AN ARSENAL TO TAME Acorn shell, trapped burr, greedy caterpillar, silk thread, ice block, homing bumblebee… twenty-three tools, a band that explains each one, and a no-stakes training room to try them out. THE MYCODEX AND THE COLONY Discover species, open boosters and silk cocoons, equip your finds, cultivate new strengths and grow your colony. Boss cards and secret species only reveal themselves to those who have faced them. WITH OTHERS Skirmish against the machine, 1 vs 1 on a single device, three-sided Battle Royale, and ranked online duels with emotes to talk back. No ads. Optional in-app purchases (Sporins) for the shop. The game is in English, French and Spanish and follows your device language.

Verdict
The clearest difference is ads: Shroom War at none against Once Upon a Tower's shown. Once Upon a Tower's advantage is iOS requirement (12.0 vs 15.0). On price, update cadence, in-app purchases and device support there is nothing between them.
