The Infernal Tube is an unlockable Launcher. It is unique from all other weapons; it has a Capacity of only 1 rocket, has no ammo in reserve and it delivers the most Damage of any hand held weapon in the game. With its single shell, it is capable of wiping out an entire enemy Wave under the right circumstances. The Infernal Tube can be exceptionally good in pre-battle bombardment but it is also very vulnerable to many things, including spies, motorcycles & decoys.
Without upgrades to speed up the aiming process, it's always a gamble that the Operator may be hit and interrupted, essentially being unable to fire. To help with this, the Infernal Tube trooper might add the Unshakable skill or Cold Blooded to alleviate the weapon's downsides. Other good skill choices include Heat Sensor and On Point.
Some players try to work around the 1 shell limitation of the Infernal Tube by using the Munition-man specialization to generate extra shells. However, this does not work well with the troops' AI. Even when the trooper has a second shell waiting, the trooper will not reload the Infernal Tube. Instead, they will try to save time by switching to any sidearm that is already loaded. Only the combination of Munition-man and the Loader skill can avoid this.
While all launchers can potentially kill the average trooper with a single hit, making this weapon seem like a senseless overkill, the Infernal Tube finds its perfect purpose when facing tanks because of their high health and armor. The Infernal Tube averages at 21 damage to each target in the Area of Effect, when applied to a tank the damage is doubled to an average of 42 (explosive V vehicle). The light tank has 40 Life Points and 2 Armor.
Light Tank: 40 life - (42 damage - 2 Armor) = 0. (on average)
Even a healthy light tank only has a 50% chance of surviving when caught in the area of effect.
Heavy Tank: 50 life - (42 damage - 3 Armor) = 11.
The Heavy Tank has a good chance of surviving a hit from an Infernal Tube, although the maximum damage is 56.
The damage is recalculated for each target in the area. Additionally, shots aimed at a Vehicle can never miss, so a shot of the Tube from a trooper set to attack "The Biggest Threat" will always connect with the tank.
- Visually resembles the AT4 with a few minor differences. Funnily enough, the RL prototype is designed to be discarded after a single use.
