- ―In-game description [Deadlocked]
The Dual Vipers are available immediately as you start the game. With use, they can be upgraded to the Dual Raptors. In challenge mode, they can be upgraded to the Mega Dual Raptors for 2,250,000 bolts.
The Dual Vipers are small, rapid machine guns with a large magazine full of bullets and a small nozzle. When firing, they appear very similarly to a normal machine gun, with no visible recoil. The Dual Raptors appear near-identically, with a metal bulk at the top (presumably to guide the ricocheting bullets).
The Dual Vipers fire bullets rapidly at enemies. While the bullets do not individually deal heavy damage, the rate of fire allows the player to unload them on enemies quickly. This makes them very useful against mobs of smaller enemies, while still useful and cost-effective against medium-sized enemies. However, against bosses and larger enemies, they will deal damage much slower than many other weapons will. As a weapon acquired early on, it will also become outclassed by other weapons.
The Dual Vipers upgrade to the Dual Raptors, which fire blue holographic bullets which can ricochet off walls and enemies. However, they must be in close proximity to acquire a new target, and their ability to do so is based on the aiming mod equipped. As it gains levels from V1-10, it primarily provides aiming, ammo and speed mods, all three of which play to the core strengths of the weapon.
Later on, the Dual Vipers are less useful as a purely damaging weapon, as they rarely deal real damage to the enemies faced later. Instead, they more useful for applying omega mods effects such as through the brainwash mod and the morphing mod.
Behind the scenes
The Dual Vipers feature a third upgrade as seen in the demo. This final form is not a dual-wielded weapon, but a fusion of the Dual Raptors that fired a single, but deadly beam.
