I'm almost unstoppable with this build. Brute power here.

Xenetix's mech
-Dual Gatling with low heat sinks-
2/10 efficacy against heat mechs. Get rekt by them, buddy
4/10 efficacy against energy mechs. Rino Boots, Shotgun and Needle Blasters can protect you, but the Super Nova perfectly hurts you.
2/10 efficacy against physical mechs. Bad HP and bad res means get rekt. Electricon/Evil Spark physical mech can disable ur drone.
7/10 for originality. Basically dual needle with bad stats and other weapons
3,3/10 overall
You need Cooling modules, better drone and another modules.You are just a starter, so that's not too bad.

So my previous build did really well until rank 5, which is where people started to overheat and deplete my mech of energy. This is my new overheat mech, which I think is doing pretty good so far. Just got to rank 4!

have 119 cooldown rexts hearters

thanks guys but now i have this weapon and this weapon and a nice shield:energy desolver mark II and energy penetrator and energy shield mark 5 and i want to use those so now what?

the best shield in the game is not the most powerful one

I usually use 10% and 15% shields..the powerful ones will just drain ur energy or heat

Suggestion?
Get rid of that heat drone, it's trash. Spam normal item boxes till you get the epic one which everyone pretty much uses. Trust me, that drone is op.
If you have no myths, you should probably try to make a physical build. Heres a suggestion. You have physical orb cannon, right? Alright, good. You only need a 60 bullet pack for this idea. You should use Blue Angel as the drone. No need for an energy module. As for the weapons, use Devastator mark III, saurus rifle, and physical orb cannon. Use cannon legs. As for the torso, try to get your hands on a Galaxus A. Module wise, you need two regeneration/cooldown modules, then put on a resistance module, then put on armor plates. Good luck!

i have 2 galuxus mark A and no physical orb cannon only heat orb

Then use the epic heat drone and the orb cannon.
