We've all seen one, complete map domination by the aliens, res at 999 and counting. Yet the marine team simply will not die. Some say "noob aliens can't finish the marines" others say "freaking marine turtles!". The problem isn't player's skill, it's tech.
Let's assume that we have a fairly balanced, typical game. The map is summit. The Kharaa have Alien Start and Data Core under control and hived, harvesters in those locations as well as Reactor and Crevice. The Marines have Marine Start and Heliport fully based, even a comm chair in Heliport. Extractors in both bases, and Flight Control and Ventilation.
Let's see what happens when each team start losing.
Assume the Marines make a hard push on Data Core and succeed in knocking out the hive and securing the area. Now the Kharaa have lost resources and important abilities:
Harvester - one less harvester to produce res.
Leap - skulks can no longer close gaps quickly or get past turrets without suffering a lot of damage.
Bile Bomb - Great at taking out sentries that are un-flankable.
Crag/Shade - Probably shade, but either way no new crags/shades can be built.
Fade - No new fades. if you have one, better not die.
Now the marines have a big tech advantage and are in a good position to push the final hive.
Assume the Kharaa make a push and heliport and take it out. A hive is dropped, currently, all this means is another place to heal.
Lets see what the marines have lost:
Extractor - One less extractor to produce res
So there is a huge difference in how losing a tech point affects each team. Because the marine team suffers no loss of tech, they are able to turtle. It is very hard to crack a base full of GL's, Shotties, and Flamers. Whereas a base full of skulks and lerks is a much easier target.
There exist only two solutions:
One: The Onos better be one hell of a badass. A serious base cracker.
Two: If the Onos turns out to be a big pansy, I fully believe that marines should have to use tech point for some critical structures such as the prototype lab.
Link goes to I&S forum where I got the tech point idea. The gist of it is that requiring marines to use a tech point for critical structures forces the marine team to expand.Tech Point Suggestion
