There's been a number of games recently where Marines cover half of the map with observatories, making it very difficult for Aliens to make any offensive moves. (Maybe someone can post a link to a replay of a game like this?) It seems to generally be an effective strategy, so effective that some people have even talked about adding in a farm cost for observatories to weaken it.
My question is, what kinds of strategies might the Aliens use against a wall of observatories? The "usual" tactics of back res biting, coordinated rushes, and sneaky tunnels don't work so well when the Marines see you coming a mile away.
One strategy I heard someone suggest (don't recall who) was to have higher lifeforms draw the marines to one place so that lower lifeforms could take down a phase gate or observatory somewhere else. I'd speculate that another Alien response could be to forget about gates and observatories, and just focus on killing Marines: once pres has been whittled down and the Marines are spawn blocked, maybe you'd have a chance of taking back some territory.
