Developer Description

Build unique Castles and challenge other players in PvP battles

Castle War : Idle Island is a Castle vs Castle battler in PvP.
Build towers, craft cannons, engage mages & mercenaries.

Rule your island, assign missions to your village. Build your Castle to fit your strategy, using the various offensive & defensive capabilities at your disposal.

Send your troops: Archers, swordmen and pikemen will lead the way to the gate of opponent’s Castle.

Use Siege weapons: Ballista, trebuchet, catapult and cannon to destroy other’s Castle towers and weapon, and protect from their troops & projectiles.

Cast powerful magic: Call a meteor strike, invoke a powerful blackhole and protect your towers with powerful arcane shields.

Build a magnificent Castle: Use wood, stone and metal rooms, to build solid ramparts and impressive towers

Mix all of those elements to build your very own Castle, from a magic tower casting huge spells, a soldier swarm on the walls of your opponent, or a rolling thunder of spikes and stones crushing its ramparts.

Use the weapons workshop to transform your standard weaponry into a state of the art piece of engineering : increase rate of fire, projectile damage, projectile speed, or weapon durability.

Prove who is the better among your friends with the challenge mode, where you can battle with them and show who have the better Castle !

Amazing! Been playing for a month straight. I highly suggest you buy the starter pack if you like the game. Hopefully someday we will get updates. Rockets or freaking lasers would be awesome. The possibilities are almost endless. My favorite game right now.

★★★★

It's a fun little Rampart style game. It has plenty of strategies by manipulating the combat timers. The game would be better if the adventure timers weren't so damn long.

I'm experienced in both the old game and this new one. Both remind me of a game I loved to play, Crush the Castle but you have your own castle now with unique options and that's the best part. Pros: *Tons of replayability *Entirely possible to play without paying *Once you thought you mastered the game's meta, there is always a new challenger Cons: *Minimal communication from devs *Rewards are sparce *Very slow to start rolling *Out of control market/shop *NO DEVELOPMENT ROADMAP TL;DR Its fun
