About the Game
Welcome to the year 3015! It’s a hell of a time to be alive.
Humanity has colonized thousands of star systems spanning a vast region of space known as the Inner Sphere. The golden age of cooperation and advancement is now a distant memory, and humanity has once again splintered into disparate factions all vying for supremacy.
In the midst of these Succession Wars, power hungry Mercenaries like yourself are in a privileged position to capitalize big time. It’s dangerous work but that’s why you’re here, right? If you’ve got an itch to blast, wreck, stomp and go all out ballistic, step inside and become your own weapon of war!
STORY
As the inheritor of a once-prominent Mercenary company, reborn in the flames of its near destruction at the hands of conspiring factions, your quest for glory and revenge will stretch light-years as you chase threads of interstellar intrigue along your journey to becoming an elite MechWarrior and mercenary commander.
THE INNER SPHERE
Home to thousands of star systems and an array of stunning biomes, the Inner Sphere is alive with activity, purpose, consequence, and variety. Systems will be captured and reclaimed, major events will unfold, and new technologies will come to light.
The rigors of war will be seen with each passing week as your relationships with the various factions fluctuate according to the relentless Succession Wars and your choices as the leader of a Mercenary outfit.
GAMEPLAY
The battlefields of the future are dominated by BattleMechs, hulking machines of war capable of leveling entire cities. As a BattleMech pilot you’ll rain havoc upon enemy ‘Mechs and targets, including tanks, ground vehicles, aircraft, advanced defenses, and reinforced bases.
Few things can withstand the power of a ‘Mech for long, and the worlds of the Inner Sphere are veritable playgrounds of destruction awaiting your shielding defense or crushing devastation.
BATTLEMECHS
"With over 50 unique ‘Mech chassis and hundreds of sub-variants, all fully-realized with high-fidelity models, damage states, and equipment, no two ‘Mechs are the same!
Whether acquired from scouring the markets of the Inner Sphere for rare and valuable chassis and equipment, or salvaging directly from the wreckage of your annihilated enemies and the spoils of war, the maintenance and operation of your BattleMechs will be vital to your success both as a MechWarrior and a Mercenary outfit commander."
THE MERC LIFE
Off the battlefield, as the leader of a Mercenary company you will need to manage all the key components of running a unit.
You’ll need to maintain and acquire ‘Mechs and equipment, hire and field MechWarriors from throughout the Inner Sphere to join you on the battlefield, and manage your relationships with the Great Houses of the Inner Sphere, all of whom are vying for your contribution to their staggering war efforts.
Of course, with each Contract comes negotiation, and with each victory comes consequence.
OTHER FEATURES
With the vast scope of the Inner Sphere and its complex system of world generation providing huge variety and replayability, the MechWarrior 5: Mercenaries experience offers no end. Outside the campaign, a fully-featured Instant Action system will allow you to customize and kick off isolated missions at any time, free from campaign restrictions.
With four-player co-op supported both within the campaign and the Instant Action system, you can experience the full breadth of the MechWarrior 5: Mercenaries universe alongside your friends.
Mods extend your game even further! Unlock the boundless creativity of the community to alter and expand the game in amazing ways. With a full editor and interface supporting gameplay mods out of the box your creativity will know no limits.

Greetings Mercenaries,
Thank you so much for all the positive responses and valuable feedback you have sent in for The Dragon's Gambit! We're excited to fill you in on another batch of fixes to smooth out your gameplay experience. This patch was released Oct 25th at 5 PM PST so your game should have automatically applied the update. We wanted to let you know what fixes were addressed in the latest patch:
- FIXED! - PS4s will no longer black screen freeze when traveling to the second mission in Dragon's Gambit
- FIXED! - Difficulty no longer resets with a game reboot on consoles
- FIXED! - Damaged Mechs with load-outs from the Olesko mission no longer appear in procedural missions
- FIXED! - Instant Action - DLC5 campaign missions now show up in Instant Action after completing it in campaign/career mode.
- FIXED! - Medium Rifle tuning fixes - Incorrect damage values at higher tiers Medium rifles above tier 1 had the +damage quirk instead of +damage percent quirk, resulting in bonuses of .05, .1, .2, and .3 damage, instead of intended 5%, 10%, 20%, and 30% bonuses in line with other classes of the rifle.
- FIXED! - Faction standing - Comstar faction standing will no longer be -400 if the player loads a campaign save file that has a game date past 3039 - The Comstar faction fix only applies to saves that have not yet loaded past 3039, saves that already have the -400 cant be changed
