Its the first create-a-weapon thread for this forum, so post all your great ideas here!
Lightning Blade:
NOTE: has the same control mechanics as the Wrench or Plasma Whip. It is a replacement weapon for the wrench.
Appearance: Looks like a glowing yellow longsword, with electricity sparks and bolts coming off it. When it hits an enemy, it works like the Shock Mod from the other R&C games, electrifying the target enemy, and any other enemy close by.
Cost: 200,000 bolts. Ammo: Unlimited

Upgrades to (final version):-
Electro Shocker:
Looks like a much larger, light-blue cutlass, with similar effects as its original version (sparks, etc...). When used in a combo, a lightning bolts shoots out forwards on the 3rd strike, if it does not strike an enemy. When used in a Comet Strike, the Electro Shocker doubles in size (only while out of ratchet's hand), and has double the range of its Version 1 counterpart.

This is actually the second or third create-a-weapon thread. Anyway...
