They mistakenly gave away the weapon as a tier 3 prize in master builders with an R2 acid storm.

It was when campaign started giving away old elites. Whoever programmed it must have thought acid storm (1) was an elite and didn't realise it was an old episode card, and also didn't realise Acid Storm (0) was an R2.

If you didn't do sell all etc on your R3 weps then you will still have it.

I emailed mobage about it. I can't remember if I posted complaining about it, but I did change my leader to acid storm during the following PvP as a protest/joke and mentioned that on the forums :p
