Superweapons Options

[SeraphsWrath]

I am mainly concerned that, since the key elements of a Scud storm or nuclear missile are Area-of-Effect Damage-over-time contaminants mostly dangerous against infantry and light vehicles, they will become of little use against ships, unless radiation/toxin damage is buffed to an over-powered degree. So, I thought of some new superweapons that might better suit naval warfare (and a possible replacement superweapon for Alexander). I didn't include any damage values, since I have no idea what the HP of ships or buildings will be.

GLA/Dr.Thax: Armor-Eater
Key elements in the GLA, led by Dr. Thrax, had noticed that, even against tanks or structures, toxins had little effect. Now, the realization that toxins alone could not hope to combat these heavily-armored warships took hold, and orders for a new weapon were issued, as the might of the US started to crush the puny wannabes of a GLA navy against the fiery wrath of China. Forced to turn to the unstable Dr. Thrax, who had escaped US imprisonment in Gitmo, GLA leaders pledged an alliance and promised facilities for their prodigal, lunatic general, desperate that he could devise some sort of weapon against heavy armor. And, against all odds, the mad scientist came through just in time to save the remnants of the GLA in the Third Battle of the Philippines with a missile that held a deadly payload of oxidizers. Upon contact with metal, the oxidizers would immediately begin reacting, rusting the armor into non-existence. It also has an effect, albeit far less dangerous, on infantry. Unfortunately, since one of the crucial reactants is water, the duration of the effect is halved when used on land.
Limitations: Land duration halved.
Upgrades:
GLA: Improved chemicals- increases damage by 25%
Dr. Thrax (starts with improved chemicals): Persistent Compunds- increases the duration of the effect by 30%

/Gen. Leang: Kanghui's Wrath
Based on the success of the Earth-Shaker and the approaching GLA and potential USA threat, Leang felt pressured to develop a new superweapon that would harness the power of the oceans. She built a modification of the Earth-Shaker that, instead of creating an earthquake, generates a series of large, circular rouge waves and shockwaves from the shell's impact site, which can overturn ships, damage water structures, and can overflow onto land, destroying ground vehicles and infantry.
Limitations: Not very strong against land structures, cannot target land areas directly .
Upgrades:
Smart Targeting: Decreases damage dealt to friendly ships by 15% (flood damage remains the same)

Alexis Alexander: Cryonic Particle Uplink Cannon (replaces the Advanced Particle Uplink Cannon)
A product of a fit of boredom and the inventive genius of Gen. Alexis Alexander, the Cryonic Particle Cannon still deals incredible damage in a precise, steerable manner, but, instead of lighting things on fire, it freezes them solid. It can be used to temporarily freeze ships together, create destructible ice-walls (note: ice walls are too slippery for infantry or vehicles to cross), or create a large iceberg that can block a channel. However, due to the synthetic nature of the ice, it melts within 40 seconds of creation.
Upgrades:
Enhanced Cryonics: Ice lasts an additional 10 seconds.
Damage: Same as Advanced Particle Uplink Cannon, + DoT to frozen ships and vehicles.
Cost: $4000
