Retan II (versatile mec)
I've built a versatile mec, the most important thing is that the mec is triforced, in the pictures you see the exterior, the core inside is rod-connected, also the weapons are rod-connected, in this way I got a three layer bot.
Thanks to the triforced "front-nose" you can put more weapons than a normal bot, without increasing the width, the bot (without flaks)is only 13 blocks width, so it's more complicated to hit.
you can exchange the weapons, plasma+flak is my favorite combination for a mec because i find it balanced against air and ground.
other good combinations could be:
2 Leviathan SMG + Plasma
2 big Plasma + SMG
you can also put a blink mod inside and/or remove the core-based propeller.
I'd like to try it with a shield module when I get one.
