About Across the Obelisk
Across the Obelisk blends roguelite deckbuilding with tactical combat, letting players assemble decks from over 500 cards and 300 items. The game follows a four‑act quest to rescue a kingdom, with each run generating new events and choices that shape the story.
Both solo and 2‑4 player online co‑op are supported, and cross‑play works across Windows, macOS, and Linux. Players control a party of four heroes, experiment with class combos, and face bosses while adapting to procedurally generated challenges.
01 / THE GUIDE
Deckbuilding and Card Pool
Players construct decks from a pool of more than 500 cards, allowing a wide range of strategic options. Cards can be upgraded, and the large selection encourages experimentation each run.
The deck also draws from over 300 items, which can be added to enhance abilities. Combining cards and items creates unique combos that evolve as the player progresses.
- Focus on synergies between cards and items early to maximize early encounters.
- Reserve high‑cost cards for later acts when you have more XP.
02 / THE GUIDE
Classes and Heroes
The game features 16 heroes divided into four distinct classes, each offering a different tactical role. Players can mix classes within a single party to discover new play styles.
Hero selection influences combat decisions, as each class brings unique abilities that interact with the deck’s cards and items.
- Pair a melee class with a support class to balance offense and defense.
- Try rotating heroes between runs to learn each class’s strengths.

Co‑op and Cross‑Play
Across the Obelisk supports 2‑4 player online co‑op, letting friends control the same party of four heroes. Coordination is required to navigate events and combat together.
Cross‑play works across all supported platforms, so players on Windows, macOS, or Linux can join the same session.
- Discuss decision points before committing to an event to avoid costly disagreements.
- Assign each player a primary class to streamline role responsibilities.
04 / THE GUIDE
Game Modes
Three core modes are available: the main story run, Obelisk mode (a tougher roguelike challenge with random decks), and a weekly challenge where decks and maps are preset for skill‑based competition.
Each mode presents the same four‑act structure but varies difficulty, randomness, or the need for precise execution.
- Use the weekly challenge to benchmark your deck efficiency against other players.
- Start with the main story mode to learn mechanics before tackling Obelisk mode.
05 / THE GUIDE
Progression and Perk System
XP earned during runs unlocks perk points, which can be spent to upgrade cards, items, or hero abilities. This persistent progression encourages repeated play.
Perk choices affect future runs, allowing players to tailor their strategy over time.
- Invest perk points in areas that complement your preferred class combo.
- Balance between unlocking new cards and strengthening existing ones.
