(Concept Enemy) Grineer Shocktrooper

[Raileks]

Basically the same as an ordinary heavy grineer but his weapon fires a pair of spikes.  The spikes deal damage on hit but remain in the target. Spikes that miss will imbed into a surface and form an electrical chain with other nearby spikes, shocking enemies that wall between them. If a target with a spike in them walks anywhere near another spike, the two will arc and shock the target, paralyzing them for a second. This holds true if hit with a second spike as well.  As soon as spikes have shocked someone they go dead.  Spikes can arc between two people as well if both are spiked.  Spikes go dead in 10 seconds regardless.

Problem with this is that you want to use the standard grineer heavy as a base, we have enough of those as is.  The spike gun not so sure about that either cause that could become a massive pain if 3 or 4 show up simultaneously and there's just spikes everywhere.
