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.

This game is so close to being fun. The graphics are cute, the monsters are all unique, and the relic system can be configured for a lot of teams. The defense mechanics are completely messed up, as a monster with 100x more atk than another monster has the same or less defense stats! This makes it insanely hard to progress and makes merging up to new monsters a complete gamble. This by itself would almost entirely fix the game.

I had about 10 hrs of fun. Music is cool, monsters are cool, graphics are cool. It's a suprisingly fun & addictive game. However the game doesn't idle while you are away. After the first 6 hrs or so the game hits a wall. You cannot micromanage enough and can only progress by updating your production line but it requires premium currency which just comes way too slowly. Even leaving the game open for hours doesn't help. I think fixing the balance issues with currency would greatly improve it

I want to love this game, I actually did love it when i first started the game. The economy system is very geared towards the whales. Meats, the item to buy monsters and combined them is purchaseable easily now, but the progression walls are too thick. All I did in the game is just watching ads after ads for the blue egg premium currency. Almost A Hero does it better, there's a sense of progression, here, pay or get stuck on level 300-400
