NEW! I came up with another version of survival,
>>>>> INFINITE SURVIVAL!
In a way like gun run, the idea is to travel and camp, travel and camp, travel and camp, and when I say travel I mean like across countries, through cities, on giant battle ships out in the ocean. you have to be clever to survive, still constant upgrades but upgrades is not the point, try to keep it real don't go out of the boundaries of weapons, no infinite ammo instakill auto aim...
I think that I shall tell you a story of a suggestion for this game because I know people really like stories.

STORY::>>:: where to start? alright this will do! I am on a mission, there is rumor of something big going down somewhere in the heart of new york, I am on a mission with an elite squad of 6 men including myself. we are going into an alley, it is raining hard, the goal is to look for anything suspicious because this is supposed to be a hideout for some corrupt people. Anyways, we hear something coming around the corner, we get up against the building walls and wait for it to get within sight. suddenly a black van skids into the alley behind us! we make a run for some cover as people pile out, they open fire and we shoot back, before long they are eliminated and we go to see what's in the van, what we find is shocking, somehow (No literally somehow, because I can't think of any good way to put this) everyone had been transported off earth because of some discovery of a perfect planet or something where there would be perfect conditions to sustain the human race without pain and all that BS. anyways it was a load of crap, the government wanted everyone gone for a while because they were doing some research on dunking little kittens in radiation and stuff, so that leaves my team and I to survive on the earth until we die or come up with a good ending to the epic battle, but anyways, we find that we're not alone and the government is after other people that know about this too, and we need to make it to them to team up and make it even more epic, that's why it is called infinite survival and that was 100% off of the top of my head and I didn't know it was getting so long so make of it what you wish. and remember, be fast, be lethal, and get a gun... the end! you know what, make that 2 guns... the end!
