What is MechWarrior 5: Mercenaries?

A first-person action simulation set in the war-torn Inner Sphere of 3015.

The campaign follows an heir rebuilding a nearly destroyed company while pursuing revenge.

+you enjoy managing contracts, pilots, equipment, and faction relations
+you want mech combat in single-player or online co-op

Not for you if...

−you prefer fast, agile shooters over deliberate vehicle combat
−you have little patience for repetitive mission structures

What players say

85% of 15,983 reviews are positive · 82% of 175 in the last 30 days

Players praise the range of mechs and equipment, destructible environments, and extensive mod support. The dominant complaint is poor allied and enemy AI, particularly pathfinding and ignored commands; many players rely on mods to address the base game's shortcomings.
