Stomp through the BattleTech universe in a 100-ton war machine, MechWarrior 5 is a mercenary campaign shooter that rewards obsessive loadout tinkering.

MechWarrior 5: Mercenaries is a first-person mech action-sim set in the BattleTech universe, developed by Piranha Games. You run a mercenary company across a procedurally generated campaign, taking contracts across the Inner Sphere, repairing your lances between missions, and gradually climbing from a rickety Locust pilot to someone who fields a full assault lance of Atlas mechs. It sits firmly between arcade shooter and hardcore sim, landing closer to sim whenever your heat management fails you mid-fight. The core loop is where this game earns its 85% approval rating. Before every drop you spend real time in the mechbay, swapping autocannons for PPCs, juggling tonnage limits, arguing with yourself about whether that extra heat sink is worth losing a medium laser hardpoint. That tinkering is genuinely satisfying. Missions themselves are varied enough to stay interesting across dozens of hours: base assaults, escort runs, demolition targets, and assassination contracts all feel mechanically distinct even if the biomes occasionally recycle. The AI wingmen are, charitably, unreliable, which is why the four-player co-op mode exists and is essentially the correct way to play once you have friends available. For newcomers to the franchise, the tutorial is functional rather than thorough. It covers movement and weapons but leaves heat economy and mech weight classes for you to learn the hard way. That said, the early campaign pacing is forgiving enough that a complete beginner can ease in before contracts start demanding precision target prioritization and component destruction. This is not a 200-hour grand-strategy game, but the underlying BattleTech systems have enough variables, tonnage classes (Light, Medium, Heavy, Assault), and weapon synergies that a spreadsheet mentality will serve you well here. Knowing that a Timber Wolf chassis with dual LRM-20s plus a TAG laser changes the engagement range calculus entirely is the kind of depth that keeps min-maxers busy. The weaknesses are real and worth knowing upfront. The story campaign is thin, more a delivery mechanism for contracts than a narrative you will care about. Enemy AI on the ground is exploitable, especially around chokepoints. Graphics feel dated in open terrain. And the base game's mod support, while present, truly explodes with the official mod support patches and the community around YAML (Yet Another Mechlab), which overhauls the entire equipment system. If you plan to play long-term, budget time to set up a few key mods because they address almost every quality-of-life complaint in the negative reviews. Bottom line: MechWarrior 5 is a solid, no-nonsense mech shooter with a loadout system deep enough to justify hundreds of hours once mods are in play. Go in for the co-op, stay for the mechbay.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
