3 stage event, so full upgrades required.
Upgrade requirements start low at 1 of each part except cores, then 1 or 2 of each part including cores for the next level, and you need to upgrade after Chapter 1 Mission 3 (I picked scope first as it's low to start with).
Very fast rate of fire and reload is slow, beware I emptied the mag of 40 in 2 shots!
Gear after stage 2 looks okay, for a change, Star Stunt (no gags please, I've already done them

For a change the weapons name actually changes at each new stage, Stage 1 - Doom & Gloom, Stage 2 - Sharktooth (probably due to the mounted blade change of design, looks a bit like sharks teeth), Stage 3 - Carnage.
Stage 3 SM's, 11* shield/crit hit/effect protection, an incomplete set again, so watch for cash purchase or ridiculous amounts of rubies to get the 2 most wanted, that part hasn't changed with GameLoft still promoting it's 'pay to play' strategy.
With the Sm's on offer here I'm hoping the weapon will actually be powerful enough to take on a base loaded with the squaddies, but who knows what will happen...
