About this game

🔥🔥🔥Rampage through a destroyed world and create the ultimate team of beasts!🔥🔥🔥

World Beast War is an idle RPG where your monsters are created, merged, evolved and sent to battle in a war to reclaim the Earth. Merge monsters to build the ultimate rampaging team!

Beasts rage and battle across the screen, including classic monsters like King Gorilla, Lizard God and more! Tap your beast to send it into battle or drag it onto another to combine them into a new, unique monster. Collect monsters and their lost articles to upgrade your beasts and defeat stronger foes.

Idle RPG mechanics let your beasts battle and level up even when you’re away, and auto-battle features allow you to manage the team while the monsters fight. Merge monsters to create powerful beasts, then merge those to create the ultimate monster! Pixel graphics create a retro gaming atmosphere with all new gameplay and clicker game mechanics.

Beast battles and apocalyptic action await in World Beast War! Download now!

fun enough, but forced ads, no. you utilize ads in many ways but to force a "monster need a break" paint notice that'll only go away if you watch a ad. nope lost me. I dont recommend the game.

Literally won't let you play the game for more than 5 minutes without being forced to watch an ad to continue. Dishonorable developer.

sometimes when you get asked if you want to watch an ad, nothing happens when you tap 'no' and the screen is locked until you click 'yes'. they know exactly what they have done.
