“Sniping” is a bit misleading in the game in general and with Zero in particular, as he has the skill tree of that name.
The game isn’t really a sniper’s game, it’s fast paced in-your-face combat and it’s hard to get one shot kills even on headshots in UVHM against anything above basic enemies.
That said, I love sniping and so try to make it work, even though I don’t have @Adabiviak 's creativity in making everything work, even long range play with the Godfinger.
The Leg Hunter is great for Zero period. If you look at Zero’s sniping tree, unless you base your whole play around stacking Critical Ascension, you don’t have to go far down the tree to get the main skills like Rising Shot, edit: meant OSOK, and Bore. Kill Confirmed, At One with the Gun aren’t necessary to still do a lot of damage with Sniper rifles. Therefore, you can make hybrid builds with the middle tree and the right one too at higher levels.
The only issue with making a hybrid build early is that you really want Deathmark/Kunai with all Zero builds at UVHM. Yes, I’m sure you can play around that, but it’s much much harder. Therefore, you’ve got twenty six points committed to the middle tree and that limits allocation elsewhere until higher levels.
The Leg Hunter is just plain great for Zero as it gives that nice little health boost on Deception plus the passive buffs. Combined with Innervate, it really helps your surviveability. For melee, once you have Followthrough, Killing Blow, and Execute, you can melee fairly well or use melee as your finisher.
Therefore, you can scrap together a hybrid with Kunai, and the first couple rows of skills in the right and left trees, but again, the math dictates that won’t be until you have sufficient skill points to do that.
My advice would be to choose a more gun or melee focused Zero and just incorporate a powerful Sniper into whatever your playstyle is, as even the most melee focused builds will still use guns until you have the points for both Kunai and Many Must Fall. The Leg Hunter is a great COM for Zero so it will fit into everything you are doing.
Have fun with Zero, of all the characters, he’s the one that makes me play with the most precision and accuracy and so made me much better at the game in general.
edit: saw your ■■■■■■■ about shotguns, they work really with Zero with OSOK and Rising Shot
