Trivia

Towers
Towers in Alien Creeps have alternated the four main tower types in excitng modern times rather than medieval times.

Machine Gun Towers
They are equivalents of ranged archers but the confusion comes when they reach Level-2 , Level-3 and Minigun as how do they have twin barrels does they do the given damage twice at a time as previously in games two archers would fire one after one.

Infantry Towers
Melee Barracks equivalent soldiers fires from a range with guns which is a common and counted as melee combat. Interestingly even with guns Infantry soldiers deal very low damage than previous games with blades and does not have armor unless upgraded.

Laser Towers
Magic Tower equivalents has a fixed damage that does not have max or least damage chances like before

Rocket Towers
Artillery and lately the druid equivalents, artilleries are very similar to rockets. All Rocket Towers fire both land and air targets but normally has extremly slow fire rate except the M.A.R.V.

Railgun

 * It has the greatest range ever.


 * First Tier 1 Ranged Tower acording to previous games that has the slowest fire rate with high damage.

Airborne
The first Barrack type to fight and block air targets in melee -(for the game melee tower´s concept of combat in which the Infantries are not ranged at all).

Quad Beam
It is the first Magic tower type (Lasers counted only for the game) to not only attack multiple creeps at once but attacking 4 creeps in a average speed, as in Kingdom Rush:Origins the High Elven Mage fires 3 enemies in a slower rate which seemed to take Quad Beam´s concept.
 * Caustic Cloud is similar to Pestilence from Necromancer Tower in Kingdom Rush:Frontiers

Plasma Cannon
This is also the first tower type to have bonus damage on every attack, more likely Plasma Cannon while focusing on a single target they may deal extra damage or attack the single target in a fast rate. The Wild Magus from Kingdom Rush Origins seems to have taken Plasma Cannon´s concept.
 * Teleport is a basic ability from Kingdom Rush's Arcane Wizard
 * Mind Control is a new version of summon golem and (skeletons from Necromancer) in Kingdom Rush.

M.A.R.V
This tower is very similar to the Kingdom Rush: Frontiers tower  Battle-Mecha T200 but can fly in a wider range and rain dual rockets with faster attack rate, however when it is by the end of its range it can´t fire out of it at all unless enemy comes by its range but can fire anywhere while enemy is inside tower range.

Heroes

 * The 3 heroes Flak, Roxie and Skybolt was originally released with the game, Cinder and Oracle was there after the 2014´s Updated version and Surge after 2016.
 * There are Limited Time Monthly Heroes that can only be taken by winning the events in every month from May 2016, The first Hero was


 * Hero Abilities also required coins to upgrade but are auto upgraded after the Updated Version.

Enemies

 * Many Creeps deal Laser dmg but it is not known who do.


 * Monthly Event Enemies are not on Xenopedia

Effects
Poisoning is known corrosive gas and also toxic which is considered Burn Effect and from the Elite 5th Area Creeps heal from toxic instead of disabling regeneration as from previous games.

Upgrades
Unlike previous games as players use stars for upgrades also reset it and as tower unlocking was separate for towers could only be unlocked and used in specific levels, here towers are researched and can be used in all levels then but requires coins needs time and cannot be reset.
