Fortress of the Sinister is a 3D turn-based strategy RPG where survival depends on tactics, team synergy, and smart resource management. You will lead a squad of specialized heroes through four deadly fortresses, battling through floor-by-floor arenas against sinister enemies, hidden traps, and rising difficulty. Build your dream squad, climb the dungeon tiers, and conquer all four fortresses!

The Origin of the Dark Stronghold

In a land drowned in shadows, four cursed fortresses rise from the void. From beneath, a sinister force commands legions of monsters. As the chosen commander, you need to infiltrate the strongholds, unite warriors from distant realms, and stop the evil before it spreads beyond the walls.

GAMEPLAY OVERVIEW

In Fortress of the Sinister, you have to survive floor-by-floor battles through grid-based arenas. Each round is a turn-based challenge where you control unique units to defeat monsters, avoid traps, and gather loot. Victory depends on how you position allies and use their powers in sync.

  • Monitor health and energy meters to decide when to defend, retreat, or unleash powerful unit abilities to shift the battle.
  • Use collected trinkets and gold after each victory to enhance your squad’s skills, weapons, or passive boosts.
  • Reach the top of each fortress by surviving ten procedurally crafted floors filled with growing threats and rewards.

How to Control

You will play entirely using the mouse, from movement and targeting to using items or ending your turn.
