How to Use the Prototype Spike Thrower

Powerful Weapon Best Used Against Large Enemies

Spike Throwers HFW

The Spikethrower is a powerful weapon that delivers massive amounts of damage, especially when using Explosive ammo. They are best used against larger targets due to their high ammo cost. To penetrate armor, they must be thrown at full draw.

Explosive Spikes

Explosive Damage HFW

This weapon uses Explosive Spikes, which explodes a few seconds after impact and deals tons of damage. However, since it inflicts explosive damage, it also destroys machine components and makes them unlootable in higher difficulties.
