—Red—Tether–>: Basic and Secret Hazard information.

Fuel is a common sight in Red Tether especially within Refinery Complex, often stored in casks bearing a helpful fire symbol or contained within Brewer-class Hyper Tankers. It is also used offensively by the Contempters, through fuel-rod missiles and plasma fireballs. Inactive Fuel forms large, flammable clouds, which can be ignited by hot engine fire, explosions, or more burning fuel. Any object within burning Fuel will be afflicted with Burn, also referred to as Fuel-Fire. In the case of enemies, this results in a moderate damage over time. For players, a timer will start: speed-crashing into another object will transfer the effect to them. Otherwise, one’s vessel will take damage.

Additionally, Engine Heat has interesting interactions with Fuel-Fire that provide risk and reward. The default heat is 100%, and at this value, there are no special effects other than one’s engines igniting Fuel clouds. Below 100% heat, one’s engines will no longer ignite Fuel clouds. Above 100% engine heat, a ship will begin to overheat while it is moving, eventually catching Fuel-Fire if it does not allow the heat to dissipate by reducing their thrust. The rate of heat buildup seems to correlate with the engine heat value.

For ships with cooler engines, Fuel becomes much less of a threat, as it will no longer be ignited when moving through it. However, in cases where one wishes to inflict Fuel-Fire, a player is then forced to rely on more creative methods such as baiting explosions over the Fuel cloud.

For ships with hotter engines, one gains the ability to easily Burn any object simply by speeding up, overheating, then crashing into it. This is a relatively useful option, especially when combined with other elemental conditions, but managing heat can be a nuisance when causing Burn is undesired, and can become very dangerous if there are no nearby objects to crash into. Additionally, as engine heat is correlated with more powerful engines, these ships generally possess greater maneuverability.

Acid is a relatively common resource, which is especially common in Chemical Spill. Often stored in casks bearing a teardrop shape or hauled by Tanner-class ships, Acid is also used offensively through weapons such as Caustic Gas launchers and Sludge Cannons. When a container of Acid is destroyed, it will expand into a large cloud, which Corrodes anything inside. Similarly to Fuel-Fire, this will cause damage over time to enemies. Afflicted players instead have a limited time to crash into another object to transfer the status to it, or else they will take permanent damage, which in addition to its damage, removes a heart container. Compared to other hazardous clouds, Acid seems to last noticeably longer before dissipating.

I’ll be honest. I’m not really sure what Pyrolysis does. It is triggered when an enemy or player is both Burning and Corroding at the same time. Through some simple experimentation, I am currently unable to figure out what its effects are.

To activate Thermal Overload, an enemy must be both Burning and Frail. The enemy will then become the center of a massive explosion, dealing hundreds of damage to itself and any enemies in a very large area around it, as well as creating a shockwave which can propel the player away. Luckily, this effect can not trigger upon the player, as players exposed to Ice will become Frozen rather than Frail. If a Frozen player catches fire, however, they will become Thawed, which instantly removes the Frozen condition.

This effect is extremely powerful, and is easily capable of entirely destroying an entire wave of powerful enemies. However, the conditions for such a powerful combo are quite rare, as Coolant and Fuel are rarely spotted together. Certain ships are capable of inflicting Frail and Burning, though keep in mind that Glacier Slayer, the ship which can deploy Coolant, does not have enough engine heat to ignite Fuel clouds.

Acid Shock is an effect that occurs when an enemy is damaged by EMP while they are Corroding. Affected targets are temporarily put into Critical Condition. If a player is shut down by EMP while Corroding, they will instead instantly take damage from their Corrosion, rather than going into Critical Condition.

When Coolant comes into contact with a source of EMP, that Coolant will become Electrified, acting as a conductor. Any enemy within this Electrified Coolant will become Frail and take continuous shock damage, which appears to be more rapid than damage dealt by other methods of shocking. Note that players inside Electrified Coolant will be Frozen, but will not take shock damage. However, EMP batteries will take damage, eventually exploding in a similarly sized area. As such, it’s best not to stick around.

This effect is quite powerful, as it stuns, weakens, and damages all enemies in a large area. Ships such as Pet Electric or Glacier Slayer are capable of enabling this combo with their elemental abilities.

Because there is limited information available about Red Tether, and because certain hazard combinations both rarely appear together and are located in late sectors, it is possible that I have missed a few combinations. For example, Magnetic Spool is a very rare hazard only located in Sectors 4 and 5, so experimentation is hard. While I have not seen any combinations involving it, they may still exist. If anybody has any information that I’ve missed, please comment it below so I can update this guide.
