There is a really cool new trailer for MechWarrior Online just released, featuring the game’s Caustic Valley map. The emphasis is on heat on this map, with it being both a challenge and an ally as you struggle to balance weapon usage with heat build-up – but also using heat to disguise your ‘mech in thermal vision. Looks like a nasty place to be! If you wanna check out the closed beta you can sign up over here. Either way, check out the trailer below.
