ZAC Assimilator

ZAC Assimilator Rank VII

The ZAC Assimilator is a unit which spawns ZAC fighters, one of the only player-allied fighters which fires missiles similar to those of the Zycon Storm. An unupgraded ZAC Assimilator spawns only one ZAC fighter. When upgraded, each base can spawn a maxiumum of 3, giving the player nine total. Any time a fighter is killed the base will spawn a new one after some time. Higher ranked ZAC Assimilators spawn fighters with better stats.

Wave stallingEdit

ZAC Fighter

A ZAC Fighter.

ZAC fighters deal fair damage, and draw considerable enemy fire. However due to the nature of ZAC fighter AI, they can cause problems for some bases:

-Fighters may clog and idle in one corner or direction of a map. They may be moved meticulously by hand to more preferable locations to fight in.

-Fighters tend to engage enemies outside of natural, unimproved ranges of most towers. If the ZAC fighters are unable to successfully eliminate enemies, enemies can simply pile up in large waves, and then advancing towards the players' base. Bases that do not have range boosts may be constantly unable to engage enemies skirmishing with ZAC fighters.

The ZAC fighter glitch

  • On the Flash version of the game, there is a glitch where if Oblivion is destroyed near a ZAC Fighter, a pair of Oblivion arms will appear on it. They are fully functional and will engage and inflict massive damage on enemies. The ZAC Fighter will continue to search for and attack enemies, and its normal weapons will remain functional. The arms will disappear if the ZAC Fighter is destroyed or if the level ends.
