Okay hi guys im actually on a map sorta like a Mini Town D you know you walk in the upgrades and it gives the upgrade building to ya ... Fairly easy ... Well I just want to know is there a way to upgrade more than lvl 2 upgrades whitout and hive (zerg 4 example) if there is just say it to me because I dont want creep to

up the design ! Hehe.
Either start off with lvl 3 upgrades or hide the Hive somewhere else.
Put terrain around the hive that you can't build on, it stops the creep.
put the hive in the water or space
I can remember a topic some time ago, but I can't find it using the search tool, where there was a dispute about whether a hive etc was needed or not to upgrade past level 3.
I think the conclusion was that upgrades past level three don't require any technological buildings - that is, if you start off with level 3 upgrades already, you won't need any hive/lair to continue upgrading higher.
I'm not sure if that was it, but it's worth trying to see if it works.
Addendum:
I tested it. You don't need any buildings (other than your upgrade building) to upgrade to level 4 and above - so to me, that seems like your best solution.
Mini Town D gives you level 7 upgrades or something to begin with anyway, but anything from 3 upwards is enough to eliminate the need for a hive.
Correct. Starcraft wasn't configured to handle over three upgrades, so there are no restriction by technology on upgrades not in the original Starcraft campaigns.
