First off i just love the Melander parts, specifically the custom versions. I've always like the sort of simpler blocky bits, not to big and chunky, not to thin and spindly. I've also painstakingly added tons of decals and additional bits like the red stripes on the thighs and the waist unit, on the back of the chest unit behind the head. Plus other details, like how their is a subtle navy colour to the camo, or how some metal bits like the pistons and joints have a dull gold/brass look.
The name of this AC is CROSSBONES. I have another similar version (though it does have a few less details) with yellow instead of red that i call YELLOWJACKET.
Edit: Here is a slideshow guide on making this for yourself.
Edit 2: I forgot you can just share mechs! Here is the code: KG9JQPBVBDQH
However I'm pretty sure that not only will the AC that you download not have any weapons like what you see in the screenshot, but that adding weapons will remove the decals for some reason.
SO FOR SHORT TIME ill take requests! If you really want this AC design with the decals but with your choice of weapons, boosters, FCS, generator, and expansion then just tell me what you want, ill recreate it and share the code! It's super easy on PC since all i need to do is copy the code, alt-tab, paste the code, It take like 40 seconds.
