Some people seem to think the game is over once the marines get a steady supply of heavy equipment, but they can be still be stopped easily if the team cooperates a bit. The trick is having a gorge on the front lines to web the marines, once that’s done they’re easy to take with any of the offensive lvls, especially fades. The gorge should keep webbing instead of attacking. If one of the heavies comes out of the web and opens fire on a nearby alien… well HMG is just uber deadly at close range ;o
If a group of marines are making a push for an area, gorges will need to build defs in groups, so if one group gets sieged or taken over the aliens can fall back to the next defensive point. If you have a group of aliens on site defending against a push there’s no point in making offensive turrets, defs and webs will help much more. So basically I’d like to see more fall back points, more offensive webbers and less turrets (when there’s aliens there as well).
It’s generally good to have 1 gorge building and webbing where the action is and one building little defensive groups around the map (consisting of about 3 defs, 3 offensives, and a few webs on the floor). It’s important to spread them out instead of building huge walls of lame, because that way the marines’ progress will be constantly hampered instead of just having to build a siege for one wall (which will end up taking out surrounding alien controlled nodes as well), they’ll have to fight through it all, once the defensive gorge gets a basic structure of defensive positions around the map it can go build them up into walls of lame at specific parts of the map that are most critical to hold, such as hive entrances (the positions the marines can siege hives from).
