A mutated Digger
Aliens:
The aliens are the main antagonist of the game. They are called "them". The scourge that is threatening to wipe out all life. Only you, with your high-tech gear and your elite military training, can take them out for good.
To take them out, aim your gun at them, and when the crosshair turns red, start shooting. It's that simple: aim and fire. Most aliens are weak and will crumble under sustained fire.
Each type of alien drops a different amount of base gold. In general, the more difficult aliens appear to drop higher levels of gold. Base gold drop is also scaled proportionally with the alien's strength, so aliens will drop more gold the longer you survive for in Survival Mode. Six out of the eight basic aliens have a mutation, or stronger version, that has increased health, damage, and speed, among other things. Mutated aliens are rarer than their lesser counterparts.
In Co-op mode, the amount of health each alien has increases the more players there are in the match. Here's the formula:
1 Player= 100% of health
2 Players= 150% of health
3 Players= 200% of health
Alien types:
Digger: Fast crawling aliens that aggressively seek you out and use their tusks to deal damage. They are quite weak and will fall under a few bullets from a weapon that is similar in power to their level. Their true danger is not in quality, but quantity.
An elite variant that spawns uncommonly has a cyan tint to it and is larger, tougher, and faster.
Tacorlion: Scorpion-like creatures that hang back at range and use their stingers to launch needles at you. Each needle deals more damage than a single Digger bite. They move slowly and are weaker in terms of health. They can act as a very effective support unit for the alien army. An elite variant that spawns rarely has a cyan tint, is larger, has more health, and has more deadly projectiles.
Stalker: Raptor-like aliens that use their strength and dexterity to leap over moderate distances. They are tougher and faster than the standard Digger, but still crumble under sustained fire. While leaping, their standard bite attack deals much more damage. An elite variant with cyan skin spawns rarely. It is tougher, requiring a concentration of weapon fire, and can leap longer distances.
Green Lady: Crawling aliens with acid sacs on their backs. They move extremely fast compared to most aliens, and if they touch you and explode they can deal massive damage. Their attack is unique among the aliens, as they destroy themselves in the process of attacking the player. They are easily dispatched and are the weakest of all the aliens in terms of health. A problem players face when fighting Green Ladies is that they can approach the player from behind, in which case they can deal tremendous damage. Green Ladies have no elite variant.
Dempster: Armored aliens that waddle slowly towards the player and a initiate spinning attack move when they get close enough to the player. While spinning, they deal a moderate amount of damage to the player and cause knockback. Demsters also can attack by biting, which does not cause knockback. While the Demster is using its spinning attack, it gains a tremendous amount of damage resistance as well as a speed boost. The player is most likely to kill the Dempster after it ends its spin. An elite variant with a cyan body spawns very rarely, having more health and damage.
Black Mayfly: Flying aliens that launches poisonous needles at the player. It is the only aerial alien. It launches needles that deal large amounts of damage. It can shoot needles in barrages of both one and three. Black Mayflies are quite weak in terms of health, and they crumble under a few bullets from weapons similar in power to their level. Elite Black Mayflies shoot more powerful needles and have more health. The elite variant is rare.
Myth371: Alien with an energy shield that teleports and launches energy spheres at players. It is a support unit that is moderately difficult to kill and has a somewhat dangerous attack. They shoot their projectiles in an arc. When a Myth371 has remained in one spot for an amount of time, it will teleport to a spot near the player and fire again. A Myth371 has medium health, medium damage, and moves very slowly. Myth371s do not have an elite variant.
Plasma Slug : The plasma slug is a slug type of alien that is encountered in Space Station. It is a very hard minion to remove, has high HP (almost the exact same as the Mambull's) It is a counterpart of the Myth371 and is much different from the Myth371 since it cannot, it has an elite version, it has much more health and damage, but moves slowly similiar to the Myth371. Plasma Slugs have not been given an official name because they have a different AI then Myth371.
Mambull: Large, dangerous alien with a resilient hide capable of absorbing extensive amounts of damage. Mambulls charge into the player, causing high damage and knockback. Circle-strafing to maintain constant distance is an effective close-range strategy, but melee weapons are not recommended due to the range of a Mambull's attack. Mambulls are the highest in health out of all the basic aliens. They do not have an elite variant.
