LOL, what is this doing here?

Dem purplish / red trees, man.

I can't tell if the mech on the upper left is a Mad Cat or a Vulture. Anyway it can jump, so there's that.

Is this really MWO? I don't recognize the mechs.

Nope. I recognize those mechs. It was from a short-lived on-line mech game called Hawken.

It was fun while it lasted.

Named after a weapon used by a Hindu deity the Chentu was designed and billed as a replacement for the Carnivore which had to be obtained by trade or Trial. With a more diverse armament mix but weaker armour the Chentu was authorized for production as all its components were produced within Clan Hells Horses space. Later variants would be produced and an upgrade to the chassis would make it a full Omni-tank several years down the line.

Whilst armed with 'new' weapons the Iwisa featured the chemical laser as its primary armament. A pair of large chemical lasers and a quartet of mediums sit in the turret and are provided with plenty of ammunition to allow for sustained firing. For anti-infantry defence the Iwisha bristled with four light machine guns in paired arrays on the side. Finally and somewhat curiously, a bulldozer attachment was added to the front of the tank. This attachment let it dig its own firing pits on soft terrain whilst also allowing the tank to serve as a clearance vehicle if needed when not in combat. It also let it shunt aside obstructions in built up terrain.

Reverse image search seems to indicate this image's origin is from Korean websites.

Reverse image search leads me to other boorus that list nakayama_miyuki as the artist. However, the listed pixiv source account is deleted.

I removed the "missing artist" tag. The artists for this triptych are, from left to right, Clover, Pencil Bro, and Feilereht.

Where's the actual missile tubes? Otherwise gorgeous.

Cool.

This is part two of: 31267.

Is this MWO or something?
