Hey... it does sort of make sense? It could be a good realistic add on (unless it already is there and im missing out?)
Of course this does seem a bit tooo specific, but however to probably make it even harder, eg; long drop down - you break your foot/feet it reduces your movement speed by 1/2, broken arm - harder to aim (its shaky)
... break your spine, forced to crawl
Hmm so forth so forth
Status effects may work similar, and could also be another Power Up idea, I mean why not shoot Poison shot gun bullets? Or being burnt(not saying it has to be visible but burns do hurt, .'. health minuses) by a grenade Or you could use those over-exaggerated effects such as freeze - slows down people.
The shovel is a different idea, as I have noticed people get stuck in the ground - why not make it a new tatic? Doesn't mean to remove chunks of land but going a few cm under the earth and jumping out at the most inappropriate times could be interesting.
