This is a map I'm making to test out Kheldrun, my Psionic Hydralisk (whom you can read about in my SC1 Campaign), the New Agent of the Swarm, birthed by the Overmind one day before Tassadar destroyed the Overmind.

Anyway, let's get to Kheldrun, shall we?

SC1 did not allow me to give Kheldrun Psionic powers, so he was just a modified Hunter Killer with 300 HP, 40 (+2) damage, 2 (+1) armor, and all the upgrades of the Hydralisk already researched.

SC2 changes this, especially with the Galaxy Editor. The creation of Kheldrun was daunting to say the least, and there's more to make for him. Right now, he's a 'classic' Hero, one that doesn't use levels. I do this because I do not know if the campaign of Wings of Liberty will have Raynor and Zeratul leveling up. So, I'm sticking with classic: Lots of HP, strong armor, Strong attack.

Stats:

HP: 300
HP regen rate: 0.5 (faster than most Zerg units, slower than burrowed Roaches)
Energy (EP): 200
EP regen rate: Same as a High Templar's.
EP regen rate while on creep: 4x a High Templar's.
Armor: 2 (+1)
Damage: 40 (+2)

Here's a list of his completed aspects:
[X] Custom Description when you mouse over his health image
[X] Special Actor
[X] Special, separate unit
[X] Burrowed version of that unit
[X] Special version of Burrow for Kheldrun which does not require research in order to use
[X] Special model (a glowing Hydralisk model with flashing eyes. All a light-blue color)
[X] Custom wireframe
[X] Custom hero icon
[X] Custom unit icon (for Revive Button)
[X] Armor upgrades added to the upgrade list.
[X] Armor upgrade icons upgrading with Evo Chamber
[X] Custom Weapon ("Psionic Spines")
[X] Upgrades and icon effects for spines
[X] Custom icons for spines
[X] Custom melee attack
[X] Custom melee sounds (planning on using the Zealot's Psi Blade sound)
[X] Custom Passive: Psionic Mind Link - Gives Kheldrun 4x energy regen when burrowed
[X] Spell 1 - Psionic Storm - special version that does not require research
[X] Spell 2 - Dark Swarm
[X] Spell 3 - Plague
[X] Custom spell animations
[X] The ability to be resurrected from a Hatchery/Lair/Hive when dead.

Aspects of Kheldrun to be Finished:
[] Special model for spines (projectile, and impact)
[] Special sound effects for spines
[] Voice sounds (this time, I can give him a custom voice)

Final touches: a voice, maybe?
An actual mission to play. Kill the Tal'darim and Dominion Forces encroaching on Kheldrun's Hive Cluster!

Mod will be created (for my personal use, sorry, however, the Test Map will still be available to the public).

Possible Additions:

"Self Transfusion" -> Kheldrun uses his powers to heal himself. Cannot heal other units.
Lurker form. You'll be able to swap back to Hydralisk form. This one is highly unlikely due to required models for this form.
Possible HP buff.
