I've decided to test a sniper character archetype as it seems like a fun idea. I was wondering though what armour should I use? I want to use something thats has a DT of 10 (forget what type it is.) Also whats a good sniper weapon? I want something with a scope but nothing like the Anti-Material rifle. Right know I have a hunting rifle which I like a lot, and I'm saving up caps to buy the scope mod. Obviously I will get a sniper rifle when the time becomes available. I would also prefer to wear a helmet over a beret.
Armor- early on, it's easy to get reinforced leather armor, which is +10 DT. In vault 34, you can get the best light armor in the vanilla game (vault 34 guard's armor), which is around 16 DT. You can get the Assassin's light armor in Dead Money, which isn't any higher in DT, but gives some +sneak and looks kinda ninja-ish. It also gives you the casino security light armor, which is around +18 DT, but makes you look like a banana. My personal fav is The Burned Man's armor from Honest Hearts, which has good DT and +3 crit, which sold me.
Sniper weapons- Ratslayer (good all-purpose sniping gun with night-scope, save ammo by using it for easy kills on most enemies that don't take a huge amount of killpower); hunting rifle- fully modded, as good as, or even superior to the standard sniper rifle, only real advantage of sniper rifle is the silencer mod. Gobi Campaign sniper rifle- fully modded, it's what the sniper rifle should be. Only drawback is you need to manage 100 lockpick through whatever means, in order to get it. AMR? It's nice to have in your stash back home for bringing out when you're up against really big game- deathclaws, etc. But not really needed, just makes the killin' a bit quicker. I'd also go fetch the All-American marksman carbine, for midrange sniping- it uses cheap 5.56 ammo, has a good scope, and packs more punch than the Ratslayer. And it shoots as fast as you can pull the trigger, and has a big clip- nice for taking out multiple mobs coming at you from medium to close range.
The DLC's didn't add any lovin' for snipers, unfortunately, so you just have the vanilla weaps to choose from.
Helmet over beret? Why? Just for looks? The couple of extra +DT from a helmet is no big deal to a ranged sniping char- you're not supposed to be a bullet sponge, anyway. You're supposed to be sneaky, deadly, and not get seen or hit. Without mods, the Beret is the best hat in the game, bar none. Any other choice, especially for a sniper who needs all the crit he can get, is gimping yourself badly.
