Antiair is a tower in Infinitode 2. It's a tower that, as the name implies, only attacks air enemies, so it's relatively cheap and gains experience faster than other towers to combat its weakness.

Unique Characteristics

Antiair has Chance to ignite, Burning damage, and Burning time as its unique characteristics.

Chance to ignite gives Antiair the ability to randomly give the Burning debuff to enemies it attacks. By default, Chance to ignite is 5% and increases by 0.2% each experience level (max 100%).

Burning damage is the amount of damage the Burning debuff does per second (limited to 3% of enemy's max HP per second and 10× Antiair's Damage). By default, Burning damage is 360% and increases by about 10% each experience level.

Burning time is how long the Burning lasts. By default, it is 5 seconds and increases by about 0.15 second each experience level.

Similar to Venom, Antiair will prioritize enemies that are not burning.

Abilities

LV	Ability	Description
4/7	Heavy weapons	Damage ×1.25
	Fast mechanism	Attack speed ×1.25, chance to ignite ×1.2
	Foundation	Rotation & projectile speed ×1.5, burning damage ×1.5
10	Aimed drop	Shot down enemies explode with 20.5% damage of their max health Unlocks with the tower
20	Ultimate	Aimed drop places a mine instead of exploding the enemy instantly, mines deal +40% damage
	Powerful	PWR ×1.1

Aimed drop: Enemies Antiair shoots down will explode in a 2-tile radius damaging nearby enemies. Even if an Antiair does the most damage to an enemy, if that Antiair does not deliver the final blow, Aimed drop does not occur.

Strategy

Antiair is the go-to tower for dealing with air enemies before you unlock Tesla and Missile. It has high Attack speed, Range, and decent Damage for a low cost. In addition, its unique characteristics ensure its targets' death outside its attack range since the duration is 5 seconds.

Check the portal(s) to see enemy spawn frequency. If few air enemies spawn but they spawn in later waves like Wave 115 and you plan on using Antiair, connect it to another main tower with a BALANCE modifier to get it to XP level 20 and equip the Ultimate. This is the only way to level Antiair fast enough since Passive XP at max upgrade level is too slow and there are few air enemies to gain experience from.

Place Antiairs on platforms that cover the majority of the map or Damage platforms. While Attack speed helps Antiair set enemies on fire faster, Damage is better since the Burning is more powerful. In terms of abilities, get Heavy weapons and Foundation. Heavy weapons is self-explanatory; Foundation is better than Fast mechanism because Foundation increases Burning damage and thus DPS.

Ultimate makes Aimed drop significantly better against ground enemies but loses the air explosion chain reaction. It is generally the better option, but with multiple Antiairs present, mixing Powerful and Ultimate for both better anti-air and anti-ground capabilities is a good option.
