For me it depends on the situation
1. Ripper > Everything
2. Photon Blaster > Everything
3. Particle Cannon > Zapper > Everything
4. Assault Bouncer > Everything
5. Holy Grail > Electro Bolt > Everything
6. Destroyer > Everything
7. Rocket Launcher or Acid Hound > Everything
I usually prefer weapons with more range since I have a katana to slice off anyone nearby.

LONG RANGE:
HOLY GRAIL

LONG RANGE:
HOLY GRAIL

Not exactly. The Railgun technically has a longer range than the Holy Grail, since the Railgun can shoot through people. . .

My opinion:
1.Ripper
2.Magnum or Photon Blaster
3.Shotgun(:D) or Terminator
4.Assault bounser
5. 50 cal.sniper(xD)or Railgun(sometimes) or Holy Grail
6.Destroyer
7.Ion cannon or Ice Hunter

My Choice

Plasma Pistol- Homing ability beats other pistols by a lot
Photon Blaster-Don't use side arms much but recommend it
Terminator- Nice range, power, and good ammo
Bubble Blaster- Homing ability, pretty much powerful
Alien Snipers (Pulsator, Holy Grail, Electro bolt)- Most damage, good ammo, end of!
Destroyer- Most powerful, Long Range and has the best stats
Rocket, Ion Cannon- Kills any enemy and long range

starter:ripper
sidearm:photon blaster
close range:particle
automatic:hailstorm
long range:holy grail
heavy:shredder
explosive:acid hound

Acid hound is to unreliable and I just don't use. I use the Ion Cannon.

ion cannon or rocket launcher i use ion because you can use more closer to you if you shoot the rocket launcher like 7 feet away it will bow you up !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Actually,come to think of it Holy Grail only has one bullet!

1.ripper:good firerate and spread

2.I do not use sidearms too much.

3.terminator:good range and damage

4.hail storm:good firerate and bouncing.

5.holy grail:1 shot kill if enemy is not shielded

6.focus beam:continous beam and kills enemies in 2-3 seconds.

7.acid hound:good firerate,good damage and can shoot curved so you can reach enemies who dont see you.credit cannon:good accuracy.good damage,good firerate.

i should not recommend,golden mauser:extra credits,but you can easily die if you use it
