Geth Infiltrator: The Real Glass Cannon

I always thought we had this build, because of the link the list with the Glass Cannon name. Then I clicked it to realise that build spec'd into fitness...Nope. This is the real deal. No fitness, all damage.

Build Link

Not for the faint of heart, be warned. This is the 66660, no fitness, best sniper in the game. A build I've played on Platinum, with success, as its arguably one of the best boss killers in the game. If you want to swap out your Javelin for your Black Widow, that is fine too.

What's the key here? Wallhack, soft cover, situational awareness. Also, killing stuff before it kills you. With the TC-PM-Headshot combo, you can oneshot Brutes and Scions (on Gold). Lethal.

Your fragility is something that needs to be managed. Be liberal with your use of ops packs (within reason, don't use them up in the first 3 waves). Know spawn points so you know which direction enemies will come from, so you don't get flanked. Maybe ease your way into this build by getting comfortable with the 65663 build first. Once I started running that a lot without dying on every wave, I felt more and more comfortable switching to a no-fitness build. Really, on the higher difficulty levels, I don't feel much difference between the two.

Power evos chosen for max damage. The ones you might want to experiment with are damage on HM versus speed and vision (can be critical in keeping you alive), Power Recharge versus Weapon Accuracy (SRs don't need accuracy, but with TC, you don't need power recharge either) and...nah, that's about it.

Edit: As mrcle123 points out, Phasic Rounds are pretty important for one-shotting your basic enemies versus Geth and Cerb especially. I kinda took that for obvious, but they're just about the only thing I would run with (occasionally AP or Drill ammo on Plat as the boss rush mode means oneshotting mooks is less important than killing bosses that have armour as quickly as possible, or Warp ammo versus Collectors/Reapers).

For what you can do with this build, in the right hands (i.e. more skilled than mine), check out this vid (again not mine, not promoting, just wanted to highlight the potential of the build- its what inspired me to switch from the standard 65663 to this one): http://www.youtube.com/watch?v=Q21vSqNPrdM
