I like to play halo on the Ratmass server. This is basically Blood Gulch with a mod that gives 2 tanks to each side. That means that instead of only 2 strategic objectives, you have 6: 2 flags + 4 tanks. The tanks are indestructible, but you can kill the driver. Any noob can tell that the side that gets all 4 has the clear advantage, but the key to getting them and KEEPING them, is not to just charge in randomly. In the long run the tanks don't belong to the side that is piloting them. They belong to the side that has it's spawn sites (and teleport site if it isn't blocked) closer to them. When you all charge at the enemy base with your tanks (or worse, ONE of your tanks) you're basically just handing them a present. OTOH, your infantry will respawn in 5 seconds, so feel free to charge the enemy with reckless abandon. If you do that well enough (ideally all at once) you can actually scare away the enemy's tanks and keep them from flagging. With proper teamwork you can take out one or two isolated tanks and then drive them back behind the base or behind a hill and set in at knocking out the enemy tanks. Once you have all of them, DON'T charge their base. Do not charge the enemy base. Form a line of tanks around the center and bombard their base, and wipe out any infantry that try to get at another tank. Park one of the tanks on the enemy teleport site. Now as the tanks bombard, send in infantry. You win.
Usually what happens is my side gets all the tanks and charges at the enemy base, and then they get all the tanks and charge my side. Rinse repeat. Sometimes one side will do the bombardment from center, and then think they've "graduated" to mobbing the enemy base and they lose their tanks. Sometimes people will actually use the right tactics. It's incredibly difficult to break a combination of tanks bombarding from center with infantry attacking directly, and you have to be totally committed and aggressive and be a good shot and know how to dodge tank rounds. The spawn camper is crucial to holding the line. He's a sitting duck, because if he tries to move the enemy can send 2 or 3 guys through the teleport and get out of the way before he rolls back over it, and they shoot him up. You get shot either way, but at least if you hold still, the tank stays there blocking the teleport. *I'm* the only one willing to do such a crucial job. I get called a noob because of this. I'm very tired of fools playing halo, but at least the Rat servers are modded to prevent teamkilling...
