Commando: A 25-ton 'mech first deployed in 2463. Focuses on scouting and close-range combat with missiles, lasers, or a combination of both. The commando is small and relatively fast, making it difficult to hit compared to heavier choices on the battlefield.

Spider: The Spider is a unique design, weighing 30 tons and armed chiefly with lasers. Unlike other 'mechs, it is intended to get behind enemy lines and wreak havoc while the enemy has their back turned. One of the most maneuverable battlemechs ever built, the Spider is extremely agile both on the ground and in the air using jump jets.

Raven: The 35-ton Raven is less focused on direct combat and instead brings electronic warfare support. The Guardian-ECM can be used to confuse enemy sensors, while the Beagle Active Probe can be used to spot concealed enemies. A NARC and a TAG can be used to guide friendly missiles towards their target, and the 'mech carries lasers and missiles to defend itself from attack. The RVN-2X, RVN-3L, and RVN-4X are currently confirmed Raven variants.

Jenner: The 35-ton Jenner is arguably the premiere Inner-Sphere light 'mech. Capable of high speeds, and equipped with jump jets for limited flight, this vehicle combines excellent mobility with a powerful energy-based armament. Several Jenner variants have a missile launcher as backup for the main laser weaponry.

Medium (40 - 55 tons)

Cicada: Compared to other medium 'mechs, the 40-ton Cicada is extremely fast at 129.6 km/h. However, it has less weight to devote to armor and is much more fragile than other 'mechs in its class. The Cicada carries a mixed armament depending on variant, generally consisting of energy weapons or a mixture of lasers and projectile weapons. Confirmed variants are the CDA-2A, CDA-2B, CDA-3C, and CDA-3M.

Trebuchet: A medium 'mech weighing in at 50 tons and first seen in 2780. The Trebuchet is built around a heavy missile armament, and can attack targets at a great distance with multiple long range launchers fitted to its torso and arms. While powerful, there isn't a lot of space for ammo, forcing pilots to make these long range attacks count. The 'mech also has several medium lasers, allowing it to hold its own if an enemy manages to close the distance.

Hunchback: Sturdy and powerful, the Hunchback is a 50-ton medium 'mech that can use a large number of weapons at once. On its right shoulder is a distinctive pod which may carry powerful cannons (including the dreaded AC-20), long-range missiles, or a cluster of laser weapons. The Hunchback also mounts weapons on its arms, making it potentially the medium with the most firepower. Hunchback variants are the HBK-4G, HBK-4H, HBK-4J, HBK-4P, and the HBK-4SP. A special Founder's version also exists, painted blue but otherwise identical to the HBK-4G.

Centurion: This 50-ton battlemech is a frontline fighter intended to be equally capable at a number of combat ranges. While the Centurion has less total hardpoints than similar 'mechs in the medium category, it can mount a balanced variety of fairly hard-hitting weapons to compensate. Standard versions of the Centurion in MWO are the CN9-A, CN9-AL, and CN9-AH. A special 'hero' version of the 'mech will also be in-game, based on Yen-Lo-Wang's personalized Centurion used during the Solaris Games.

Dragon: The Dragon is a 60-ton heavy battlemech that is defined by speed and close-range firepower. At 86.4 km/h, it is much faster than most other heavy 'mechs and fights with a combination of medium lasers, light autocannon, and missiles. Announced dragon variants are the DRG-1C, DRG-1N, and DRG-5N.

JagerMech: The 65-ton JagerMech is a long-range weapon platform. It focuses on a heavy armament of autocannons, carrying a mix of both light and medium guns to engage targets at long range. In the BattleTech universe, the JagerMech is also an excellent anti-aircraft platform; in MWO there are currently no plans to implement any kind of air component beyond 'mechs with jump jets.

Catapult: An iconic inner-sphere 'mech, Catapults weigh in at 65 tons and are intended for heavy fire support. Standard versions carry a large supply of long-range missiles and heavy launchers on either side of the hull, along with lasers fight at close range. Some Catapults sacrifice missile firepower in exchange for bigger energy weapons. Confirmed are the CPLT-A1, CPLT-C1, CPLT-C4, and CPLT-K2 versions of this 'mech. A visually unique Founder's version exists with identical capabilities to the CPLT-A1.

Cataphract: A 70-ton heavy 'mech introduced in 3025. The Cataphract has heavy armor, allowing it to survive a lot of punishment. The 'mech fights with a combination of autocannons and lasers, although some variants supposedly carry a more varied mix of weapons. The Cataphract has jump jets that allow for limited flight around the battlefield.

Orion: The personal Battletech chassis of Alexandr Kerensky himself, the Orion is a heavy 'mech that weighs in at 75 tons. With a varied weapons load out, good armor, and average speed it's a 'mech favored by Battlemech pilots who like options on the battlefield. The standard ON1-K variant comes with energy, ballistic, and missile hardpoints.

Assault (80 - 100)

Victor: At 80 tons the Victor sports relatively light armor compared to others in it's weight class. Relaying instead on JumpJets for maneuverability, as well as it's main weapon , the heaviest Caliber Autocannon available, the Autocannon 20. Dual Medium lasers, and short range missiles round out it's accompaniment of weapons. The Victor is an assault 'mech favored by pilots who are able to utilize mobility and heavy focused firepower to great effect. The primary variant, the VTR-9B comes with energy, ballistic, and missile hardpoints.

Awesome: One of the Inner Sphere's most common assault 'mechs, the 80-ton Awesome is chiefly meant for fire support. While it has heavy armor, the main feature is a devastating energy armament consisting of 3 particle projection cannons. Other versions of the Awesome have a more balanced array of weapons consisting of long-range missiles and lasers. MWO currently has the AWS-8Q, AWS-8R, AWS-8T, and AWS-8V Awesome variants.

Stalker: An 85-ton battlemech intended to bring heavy fire support at any distance. The Stalker has a lot of missiles, in both long- and short-ranged varieties. It also carries large and medium lasers, powerful in their own right and especially useful should the missile supply run out. The Stalker, like other assault 'mechs, is slow and bulky, and the sheer number of weapons can cause overheating.

STK-M Misery (hero)85535001.0648.6

Highlander: This 90-ton Star League design first saw service in 2592, making it the oldest announced 'mech to be featured in MWO. Despite its age, the Highlander is tough and packs modern weaponry; lasers, missiles, and a gauss rifle. Surprisingly for an assault 'mech, the Highlander is equipped with jump jets, and in a pinch can use its weight to literally crush a smaller enemy from above.

HGN-HM Heavy Metal (hero)90535441.3649.5

Atlas: No other sight is feared quite like the 100-ton Atlas assault 'mech. This large, slow vehicle makes up for these shortcomings by carrying massive quantities of armor and more weapons than any other 'mech currently in the game. The Atlas carries several lasers, both short- and long-range missiles, and a heavy autocannon to bring pain at close distances. Atlas variants are the AS7-D (including a Founder's version), AS7-D-DC, AS7-K, and AS7-RS.
