Your goal in Fortress of the Sinister is to lead your squad of heroes through a dangerous fortress, defeating all enemies and overcoming tactical challenges in each zone. Control your heroes and interact with the game world primarily using your mouse. Left click on a hero to select them, then left click on a grid space to move, or an enemy to attack. You'll also use left click to activate abilities, select menu options, and confirm actions during your turn. Gameplay is turn-based. You'll move and act with each of your heroes, then the enemies will take their turn. Use your heroes' unique abilities, positioning, and environmental elements to outsmart your foes. Progress by completing objectives in each encounter, which often means eliminating all hostile units. Keep an eye on your heroes' health and ability cooldowns. Strategic use of cover and focusing fire on key targets will help you survive and advance through the fortress's four challenging zones.
Positioning is Key - Always consider where your heroes will end their turn. Keep ranged attackers safe and melee characters engaged. Ability Synergy - Look for ways your heroes' abilities can combine. Stun an enemy with one hero, then hit them hard with another. Focus Fire - Concentrate your attacks on one enemy at a time to eliminate threats quickly and reduce incoming damage. Use Cover - Take advantage of environmental cover to reduce damage from ranged attacks, especially for your squishier heroes. Scout Ahead - If possible, use characters with extended vision or movement to peek around corners before committing your whole squad. Manage Cooldowns - Don't waste powerful abilities. Save them for tougher enemies or when you need to turn the tide of battle.
