The following weapons are recommended for the indicated situations.

Melee: It is the best way to attack at close range.

Nucleon Charge Rifle: It is the best sniper rifle, but it requires time to charge once you look through the scope. It is best used when in a safe position at far range.

Riot Cannon: It has a wide blast radius and does a large amount of damage. However, it has limited ammunition capacity, but it can be upgraded.

Thermo Rocket Cannon: It is a heavy weapon that quickly locks-on to an enemy with a guided missile. It rarely misses but has very limited ammunition.

V32.CYBR Corrupt@r: It turns an enemy to your side temporarily. They will then immediately attack the closest enemy, but it is not as effective as you can be. It is best used when you are outnumbered.

X18 Scrapmaker: It does not require reloads, but it has a small amount of cooldown before it can be fired.
