ohh hourglass, there's just so many things to do on this map. its why I like it.as Nod, you have to make an early flame rush of at LEAST 6-8 tanks. now that the game's been out for 2 months people who are on GDI know how to defend here. all you need to foil a flame rush here is a horde of med tanks and some mrls's and some sydney/PIC.
another fun nod strategy is taking 2-3 Artillery onto the top of the hill and pound on the big flashing stick on the GDI refinery. if the GDI team is sleeping, you'll have it dead in seconds. otherwise, you rack in the points until a tank finally comes and gets you.
and also another fun trick for Nod is to get 3-4 artillery on the side roads with technicians for repair. have them all pound on the weapons factory or infantry barracks. Like the refinery rtick, if GDI is sleeping you'll kill them both. but if you do it early enough they will never see it coming until they hear "GDI Weapons Factory Destroyed".
The best tactic for spying is using the rock at the top of the hill I have dubbed as the "spy rocks". on either side of the hill on the very top is (coming up the Nod side) a small rock on the left side. get in a buggy and hide behind it for a totally clear view of the GDI base. and in the center of the top get a humvee behind the bunch of rocks there and sit there for a perfect view of the Nod base to warn your team when a flame rush is coming.
Once the GDI AGT is killed from a flame rush, just use stealth black hands to take out the rest of the GDI base.
If your on GDI and your AGT is killed from a rush, dont worry. this is probably the only map where you can survive with no defenses. there are only two ways into your base, so stick a mammoth in both entrances and completely block them off, and then mine the sides of the mammoth to make sure no stealths sneak by. keep meds and mrls's behind the small metal walls for support, and a contingent of hotwires and engineers about to repair your defense forces after a rush and to disarm any beacons that may have been set by a smart stealth black hand that got by.
Easy enough. I always use these strategies and they aways work.
