MechWarrior Online is comprised of two distinct game types: Quick Play and Faction Play. Quick Play is currently comprised of six game modes: Conquest, Assault, Skirmish, Domination, Escort, Incursion. Faction Play is currently comprised of three game modes: Siege, Counter Attack and Scouting. While simply destroying the enemy team is always a viable option, teams that leverage the full depth of role warfare can utilize their specializations to secure other victory conditions specific to certain game modes.
- Destroy the Enemy Base (or)
- Destroy all Enemy combatants and have less Base Damage than the Enemy Base (or)
- Have a Base Damage advantage when the match timer expires
To secure victory players in the Incursion Game Mode pilots must ensure the integrity of their Team Base, contending for essential Fuel Cell Supply Points to power key Support Towers for use in the fight against the Enemy forces and their Base.
- Control the Communication Beacon for a cumulative total of 1 minutes (or)
- In the event of an expiration of the match timer, have controlled the Beacon longer than the Enemy team (or)
- Destroy all Enemy 'Mechs and enter the capture radius with more time left in the match than is needed to complete the capture
The primary goal of Domination is to claim control of the central Communications Beacon. Each team will start a game of Domination with a team countdown timer set at 1 minute. To complete the objective and emerge victorious your team must hold the Communication Beacon for a total duration of 1 minute throughout the course of the match. The first team to reach 0:00 will be the victor.
Escort is an asymmetric Game Mode for Quick Play. Teams are assigned the role of either the Attacker or the Defender, with separate objectives and win conditions for each side.
The Defenders must ensure that the AI-controlled, ECM-equipped Atlas VIP reaches its destination at the Extraction Zone in time for extraction.
The Attackers must do whatever they can to stop the Defenders from achieving this goal.
- Be the first to collect 750 Resource Points (or)
- Possess the most Resource Points when the match timer expires (or)
- Destroy all Enemy 'Mechs and control a sufficient number of Capture Zones to guarantee a victory by Resource Points in the remaining Match Time
The primary goal of Conquest is to claim control of the Capture Zones scattered throughout the map. Each Capture Zone under your control provides your Team with Resource Points, at the rate of one Resource Point per second, per Capture Zone. The more Capture Zones your Team controls, the faster you'll ensure victory. Teams who focus too greatly on combat do so at great risk; a well-coordinated Lance of Light 'Mechs can easily snatch victory from an enemy too focused on sheer firepower.
- Capture the enemy base (or)
- Destroy all Enemy 'Mechs
Assault challenges each Team to capture the enemy base, while simultaneously protecting their own. Teams looking to achieve victory through a base capture will need to divide and conquer; a well-armed diversionary force can mount a convincing distraction to draw the enemy's attention, while your faster 'Mechs go for the base capture. Mixing and matching complementary roles, feinting tactics, and effective communication are all key to winning an Assault match through tactical means. However, when tactics fail, brute force can still turn the tide.
- Destroy all Enemy 'Mechs
Skirmish is 'Mech warfare at its most simple. Skirmish contains no side-objectives; no bases to capture, no resources to collect. There is only combat. Scouts and Support 'Mechs may shift their attention toward locating enemy forces or wearing them down at long range, while Brawler and Assault 'Mechs may focus their immense firepower to crush the front line and scatter the ranks. Whatever strategies are employed to achieve it, there is only one simple goal: total annihilation.
- Attackers: Destroy the Space Defense System (SDS)
- Defenders: Protect the SDS from destruction
Siege represents the initial moments of a planetary invasion, where attackers look to cripple their enemies' orbital defenses in advance of the full invasion force. To accomplish their objective attackers will first need to penetrate the massive blast doors that protect the base. Built by the ancient Star League specifically to keep 'Mechs at bay, the doors can only be forced open by destroying the nearby generators that power them.
Once beyond the gates the attackers must destroy the three generators within the base that power the Space Defense System's massive Naval Gauss Cannon. When the three generators have been destroyed, the backup power system in the SDS gun goes online to maintain full operation, opening its blast doors to vent the excess heat at the cost of leaving it vulnerable to direct attack. Upon destroying the SDS power system the attackers have achieved victory, and will be able to continue the invasion unimpeded.
Attackers can increase the odds of victory for their Faction in the Siege game mode by launching missions in the Scouting game mode prior to the Siege.
- Attackers: Destroy all Enemy 'Mechs and the Mobile Field Base to retake the Space Defense System
- Defenders: Destroy all Enemy 'Mechs or survive until the timer expires
In the Siege Counter Attack game mode the planet's previous defenders must now go on the offensive as the attackers, and attempt to regain control of their base and the SDS located within. To achieve their goal the attackers must not only destroy the Enemy team, they must also destroy the Mobile Field Base they established to further coordinate their attempted invasion.
- Attackers: Gather intel from defender Data Points
- Defenders: Protect Data Points from the attackers
Unlike the 12v12 respawn system found in the Siege and Siege Counter Attack game modes, Scouting is a 4v4 single-spawn game mode focused on capturing or protecting Data Points.
