I am planning on getting the Plasma Rifle from doing the ''  The Replicated Man'' quest however to also get the Wired Reflexes perk I would have to rat out the Android to Zimmer which will give me bad Karma (equalizing the good karma I got from the quest) So what is better? I am trying to go all out good on the game but is the perk worth it? and can I still reach maximum positive Karma by doing this? 
 
Thanks.

Definitely go with the A3-21 Plasma Rifle (I think that's what it's called). It's one of my favorite guns in the whole game, especially when you devote some points to Energy Weapons.

I think it's definitely worth it to get both rewards. Sure you end up canceling out your Karma gain, but there are more than enough opportunities to max out your good Karma so it's worth it in my eyes.

The perk really isn't worth it when you consider how many other V.A.T.S. percentage increasing stats you get, such as Gunslinger, Commando and Sniper. I found that by the end of the game I was getting 95% on every body part from a good distance away making Wired Reflexes unnecessary. However, if you wish to get the perk first tell A3-21 he is an android, then ask if he'll let you kill Zimmer. Then, go to Zimmer, tell him who the android is, and then kill Zimmer and his bodyguard, Armitage. This way you'll get bad and good karma which balance each other out and the android will still remain friendly towards you. It is extremely easy to reach max karma either way in this game so don't worry about it too much.

I just gave him that thing that convinced him the android was dead. also wasn't it dr. zimmer, and not zimmerman? Not trying to be a dick, just wanna see if i'm remembering correctly. 

Get neutral Karma. You can always get more good Karma elsewhere but the rewards from that quest are too good to pass up so get both and go with neutral.

The plasma rifle is a great gun for most of the game, and the Wired Reflexes perk is definitely worth it.  You'll have plenty of opportunity to raise your karma back up from doing other quests.  Or, you can just go to the Church of Atom and donate caps to get your karma back up.

" @NekuSakuraba: I bumped into some girl in the Rivet City Marketplace and she gave me something to give to zimmer. It convinces him the android's dead. All you get are caps and good karma if you do it that way.  "

" @NekuSakuraba: It's all your preference. I don't wanna make a suggestion either way because I've never used the gun, so I don't know how good it is. If you're going for good karma do what I did.  "

" @NekuSakuraba: well if it was me I would do the last one since I didn't give a shit about my karma. at the time I didn't know the rewards so I just picked the easiest one. One thing, I think you're wrong. I'm pretty sure if you rat out the android you get bad karma, not none.  "

Just did it, any idea where to find some ammo for the gun?
