Your OP combos and when to use them- All non-prestige guns

Okay, so, here's your combinations for under level 30 that will make you OP. all these guns are under level 30, so you can do any of these at a low level.

Infect:
#1 (Best): Model - Deagle
This is my infect combo and it will NEVER change, even with prestige guns. TBH, the only thing better than this is ray gun. This combo is insanely OP. Because you don't need to do long-rage combat in infect, the model's one shot will create a 6-8 block no-touchie radius around you. The desert eagle is your reloading gun. When you spend all four of your model's shots, use the deagle to pick off any survivors of your model fury. You'll want to strafe backwards when doing this. The deagle can also weaken and pick off any zombies at long range. I like to do this zoomed in, as it increases accuracy, but it's almost as potent zoomed out. Firing a deagle from the hip into a crowd is perhaps the best way to get some weak zombies.
#2 AK 47 + M9
This combination, while ammo intensive, deals very good knock back to zombies and allows you to get a wide berth when running while dealing massive damage. However, you MUST conserve ammo.
#3 (Second best): Spas12-(Any secondary)
This combination is good, but it will take 2-3 shots to drop any zombies. I'd camp with the ray-gunners if I were you, and I'd occasionally go out and pick them off. Since you don't have the best guns, go out and pick off one or two zombies, then come back.

TDM:
#1 Long range: MSR-Deagle
This combo will make getting kills very easy if you're careful, and if you watch your ammo count, you can easily EMP and maybe nuke. But watch your AMMO. The MSR has a faster fire rate than you need, so don't rapid-click. The MSR is like the dragonov + the barret. 6 round clip, average of the dragunov and barret, the automatic fire of the dragunov, the one shot head shot of the barret. My advice is to shoot them, see if its a headshot, and then shoot them again if it isn't. This will save a ton of ammo. If you're going up against crowd, spam the MSR until it reloads. You'll probably get 1 or 2 kills from this, and finish the rest with deagle. It's lethal. This kind of strategy makes people go "WAS THAT RLLY MSR DEAGLE" because it can drop 4 people extremely fast at the cost of a lot of ammo.
#2 long range Dragunov + Deagle/M9
Same strategies for MSR, really, except always fire 2 bullets. This pretty much instakills the target, but it's ammo costly. I like to think of the Dragunov as a slow Isolator that uses a ton of ammo.
#3 long range L118A + Secondary
This is your most basic combo which can be surprisingly lethal. You just need to hit the target on the head, literally.

#1 Assault: Deagle + Famas
I rarely use this, but it's quite deadly. Find a choke point and shoot at anything that moves, but make sure you don't waste ammo dropping targets. Eventually, you'll need to reload, so you can hide behind the corner with your deagle and pop out if anyone comes close. I'd recommend aiming the camas as it's more accurate and kills faster this way, but it's not reqired.

More coming soon.

 

Not really, MSR deagle is very effective, especially with large groups. You can deal massive spread damage with deagle while strafing so you don't take any damage, and then pick off who's left with MSR.
