Fortress of the Sinister

Four fortresses stand between you and whatever's hiding in their vaults, and each one is packed with enemies that don't play fair. Fortress of the Sinister hands you a team of characters and a turn-based combat system where every move counts - misjudge a fight and you're retreating to patch up, not pressing forward.

The pull is the loop: clear a room, gather resources, spend them on abilities that make the next room less brutal. It's tactical in the way Tactical Games fans expect - no button-mashing, just reading the board and deciding who swings first.

Each fortress hides secrets worth digging for, and with four to work through, there's always a next objective pulling you forward. It runs straight in your browser, no download, so you can jump between fights whenever you've got ten minutes.

If you like the exploration itch scratched alongside the strategy, it sits nicely next to other Adventure games on the site - same curiosity, different toolkit.

Lead your team through four fortresses, defeat the enemies inside using turn-based combat, and reach the end of each one alive. Gather resources as you go and spend them to enhance your characters' abilities between fights.

Pick your moves each turn based on what the enemy is doing rather than just attacking blindly - the fortresses get tougher, and a well-timed ability beats brute force. Explore each area fully before moving on; secrets are worth the detour.
