About MechWarrior 5: Mercenaries

MechWarrior 5: Mercenaries places you in the year 3015, amid the fractured Inner Sphere where Great Houses vie for dominance. As the heir to a once‑prominent mercenary outfit, you travel across star systems seeking glory, revenge, and profit.

The game mixes large‑scale BattleMech combat with mercenary management. You acquire, repair, and field dozens of unique ‘Mechs, negotiate contracts, and influence faction relationships while enjoying single‑player, co‑op, and mod‑driven content.

01 / THE GUIDE

Story

You inherit a mercenary company that was nearly destroyed by conspiratorial factions. Your personal quest for revenge and fame stretches light‑years, pulling you into interstellar intrigue that unfolds throughout the campaign.

The narrative follows your rise as a MechWarrior commander, with each contract and battle shaping the path toward becoming an elite mercenary leader.

  • Record the outcomes of each contract to see how they affect your reputation.
  • Focus on missions that align with your revenge goal for a clearer story direction.

The Inner Sphere

The Inner Sphere contains thousands of star systems, each featuring a variety of biomes. Systems can be captured or reclaimed, and major events occur as the Succession Wars continue.

New technologies emerge during the conflict, influencing both battlefield tactics and the economic landscape for mercenary outfits.

BattleMechs

Over 50 unique ‘Mech chassis and hundreds of sub‑variants are presented with high‑fidelity models, damage states, and equipment options, ensuring each machine feels distinct in combat.

You can obtain chassis by purchasing them on Inner Sphere markets, salvaging wrecks, or looting spoils, then maintain and outfit them for missions ranging from tank destruction to base assaults.

  • Balance armor, firepower, and mobility when customizing a ‘Mech for a specific mission.
  • Repair damage promptly to avoid performance penalties in later engagements.

The Merc Life

Beyond combat, you manage core components of a mercenary outfit: acquiring and maintaining ‘Mechs, hiring pilots from across the Inner Sphere, and handling relationships with Great Houses.

Each contract involves negotiation, and every victory triggers consequences that affect reputation, resources, and future mission offers.

  • Maintain a diverse pilot roster to cover different combat roles.
  • Negotiate contract terms that secure long‑term resource stability.

An Instant Action system lets you launch isolated missions at any time, free from campaign restrictions, and supports four‑player co‑op both in campaign and Instant Action modes.

Steam Workshop integration provides a full editor and out‑of‑the‑box support for gameplay mods, allowing community‑created content to expand the experience.

  • Use Instant Action to test new ‘Mech builds before committing them to the campaign.
  • Browse popular mods to refresh gameplay mechanics or add new content.
