War of the world

The Vile, a primal yet affective species from another planet. They settled here only to consume without halt and to destroy what remains of mankind. They don't own any technology but they have mastered the art of mutation and body transformation. They eat and corrupt other humans like a plague with no cure. Fellow humans would turn into grotesque monsters only seeking to spread the infection.

AAP stands for; Anti Armour Piercing. These suits not only enhances the soldiers performance in combat, but grants great protection against small caliber munitions and Crawler claws. APP suits can also be modified and upgraded to the users liking.

A Crawler is the lower life form of the Vile. Mostly used to outnumber or to oppress. If unprepared, they can kill and corrupt in seconds. They are as big as a dog, they are bipedal and they have sharp claws and teeth made for digging into flesh. Thankfully they are pretty weak and can be killed with pretty small caliber munitions.

RPAS stands for; Rocket Propelled Action Shell. These weapons would dislocate your arm or break your wrist from the shear force of the 56 caliber rounds in the weapon, if you aren't using an AAP suit. As the name explains, these weapons have extremely heavy ammunition that are explosive and propelled by a small rocket inside the bullet, turning it into a micro missile with full auto capability.

Tyron mechs are 25 foot tall suits of armor made to fight the bigger and stronger Vile creatures. These mech suits are named by the steel they're made out of, Tyron steel. These machines cannot work unless they have a pilot.

Tyron steel is a steel alloy which was mixed with an extremely rare crystal called Pyron. Tyron is used mostly for its extreme resistance to temperatures and it's extremely high conduction.

Hollows are a direct ancestor to the Infested. Once an Infested is done mutating, it becomes a Hollow. A tall, lanky, disproportionate, armoured and aggressive being. These creatures are much smarter than Crawlers and can kill a strong soldier given the opportunity to do so. Sadly, these beasts are also very resistant and quick. Which means you need higher caliber munitions to deal with this threat. But RPAS always does the trick!

When a human is corrupted by the Vile cell, it's body morphs into a Bike through the modification of DNA. When humans are recently mutated they become very recognizable and aggressive quickly. Infested are easily identifiable thanks to the split jaw mutation all Vile have.

Ravagers are much rarer than Hollows but are one of the multiple specialized Vile creatures. This until specializes in digging and crushing. Ravagers are big, six legged, with a cockroach style bulletproof shell and big claws that can easily snap an AAP suit in half. Most encounters with these creatures is when they suprise attack you by popping out of the ground when you least expect it. They also help destroying structures and digging tunnels to benefit the horde.

V-Blades are swords used by soldiers and Tyron mechs who have a budget. These blades create extremely high vibration along its sharp end. In result it creates extreme heat and, thanks to the extremely fast side to side motion, it can go between to molecules extremely easily. These are the replacements for the plasma blades because of the inhumane nature of plasma.

Warlocks are soldiers who can use their emotions to bend space, time and matter with the elemental limitations that grants their DNA. They are pretty common and their power isn't as powerful as you would imagine. But the more 'gifted' Warlocks can have devastatting powers that can be used at their will.
