nuclear explosives

[VuDu]

Well i tought when you're with exploder you get explosives and kill tanks but in late game with infernal tanks and titans exploder is almost usless eaven if it has 6 explosives on max upgread and buying new tank with weapons is just not very good option.So I suggest there should be a nuclear explosives.

Nuclear explosives:
Cost: 13 300g (or less i don't know if this is to much)
Demage: 3000(on explode) without upgreads
Range: (AoE) 1000
After exploding it lefts poison gas wich deal 800 dmg/s ; slow enemies with 30% and AoE 800. Last 10 sec.

Upgeads:
1) +3000 dmg(on explode) Cost: 3700g
2) +4000 dmg(on explode) Cost: 4900g

I'm not sure if my calculations are right so correct me if I'm mistaking. :| :?
And also simular can be made a nuclear bomb ; factory wich spawns nuclear exploders ect
