My personal favorite weapon is the Answer, with the SPNKr Prime as a close second. Let me know what you think.
Not sure what is the most OP weapon but the answer is pretty OP. I also like the blaze of glory!
My favorite is the MA5D Assault Rifle.
But in all seriousness, things like Sniper Rifles, Rocket Launchers, Plasma Pistols (for EMPing vehicles) are always useful.
Jorge’s Chaingun, otherwise known as the ‘Etilka’.
3rd person view, similar TTK with the Answer, base movement speed unhindered, and internal buffs to the player holding it.
Answer, whiplash, and blaze of glory
On second thought I really like the whiplash and H2 Beam Rifle Alpha.
