Alright, I was just randomly thinking about a defense I have not seen on starcraft my self (yet it could have been done already, and i didn't know due to inactivity) I was thinking about trying to make this..

I wanted it to be PvP based (Player Vs Player).
What I was thinking was every player gets their own little arena. There would be a spawn of units, but the same unit!
It can have like 9999hp (or more?), but it would only start off like at 4% health (just a number, just want to get the concept down).

Then it would go on to walking its course (which i am picturing in a square; in the middle of what its walking is where the players defenders would be. Then you would lose when you get too many units in your area.

Then there could be a section for you to 'upgrade' the offensive creeps your sending. So player1 could 'upgrade' his health so his next (and continuing waves) would be 6% health, rather than everyone elses non-upgraded 4% health.

Then you could also 'buy' spawns, to add +1 spawn (I'm picturing a max on this)

Player1 would send to Player2, Player2 to Player3 and so forth.

As for the defense, I figured just the normal units, hydra, marine, goon, etc. etc. with upgrades available to each. I also thought instead of adding Marines/Ghosts to the defense, like you could buy an 'scv' to build 1 bunker that would spawn a random Combo of Marine & Ghost. Then SCV would get removed. That was just some ideas on the defense.

Also, if it would be worth it, there could be some kind of 1-speed Upgrade, like normally spawning Zealots, but once bought, spawn Fenix
I also thought maybe the units that spawn should be random (but share the %health) so like, if it was a Marine spawning, people would buy just the unit that does the best against it. Like have it randomize between a few different ones.

I'm not sure if this would all be possible (i assume so, it would just take some work to do it)

Anyone think its a good idea? Or have any comments on it?

I hope i made everything clear, any questions please ask.

It sounds good, but this is a bad idea:

It'd really suck to have Player 1 be a pro, player 2 be a pro, and 3 and 4 be nubs. Player 2 has to chew through two nubs before he can even get a crack at player 1, while player 1 has nubs against him and can attack player 2 at his own will. This makes people strategically place themselves behind the person they want to kill, I'd make it so everyone sends to everyone or a person selects the target he wants units sent to.

Well, now it's just like line tower wars/madness map if you let the players choose which player to send it to.

I know that may be the case in some games, but if you could choose where its sent, people can just send to the strongest. or friends ingame send to everyone else but each other.

Then have it send to everyone, I assure you no real defense players will want to play this map if they are forced to send to one person while someone else can bombard them.

Spawn Defence.

Maybe you can make this game teams, so that p1 and p2 send to p3 and p4, and vice versa.
