In the crowded landscape of indie games, sometimes a simple rule can create profound complexity. Enter Unto Deepest Depths, a punishing new roguelite and turn-based strategy game from McCollum Games, poised to challenge veteran tacticians and newcomers alike. With a core mechanic that forces perpetual motion, this dark fantasy adventure ensures every single turn is a high-stakes decision.

The Rule That Changes Everything

At its heart, Unto Deepest Depths is a turn-based tactical game. You build and command a party of units, navigating procedurally generated maps and conflicts. But here’s the key twist: Every unit must move and attack every turn.

This simple constraint fundamentally alters the rhythm of battle:

• No Camping: Forget turtling up! You can’t sit back and wait for the enemy to come to you or spend a turn solely buffing your troops. You are constantly advancing, forcing you to prioritize targets and positioning with brutal efficiency.
• Destructive Dominoes: Since all units must act, careless attacks can put your own allies in harm’s way. Using a powerful but area-of-effect ability might wipe out a handful of foes, but if it forces your Lancer into a dangerous position next turn, was it truly worth it?
• Depth in Simplicity: Unlike games with complex action-point economies, each unit has only a basic movement and one core ability (an attack, a heal, or a summon). The depth comes not from the number of choices, but from the consequence of the choices you’re forced to make given the movement mandate.

Building Your Descent Party

Your journey isn’t just about tactical combat; it’s also about strategic resource management and party building. As you venture through the depths, you’ll earn experience to:

• Hire and Promote: Expand your roster with various unit types—from basic Peasants to more specialized units like Knights, Archers, Mages, and Healers. Promotions unlock Elite and specialized units, broadening your combat options.
• Upgrade Wisely: You can spend resources on powerful unit upgrades. These might be simple health boosts or damage bonuses, or more complex buffs like death saves or bonuses for adjacent allies. With an upgrade-tree structure and limited resources, you must carefully choose who to specialize and how.

The Dark Unknown

The game promises a grueling roguelite experience. Each run will take you through five unique, procedurally generated biomes, culminating in encounters with menacing creatures and powerful bosses.

The procedural nature of the conflicts, combined with random challenges and events you’ll face along the way, ensures no two expeditions will be the same. The narrative centers on venturing into the unknown to “vanquish the horrors below,” providing a dark fantasy backdrop to the unrelenting tactical challenge.

Unto Deepest Depths is one to watch for fans of demanding turn-based strategy. The promise of a game where a single, simple rule creates a vast ocean of strategic possibility is an exciting prospect. Prepare to descend—just remember, you can never stand still.
