Reach Beta - Overlook Strategies

This gametype actually isn't all that deep, but it is challenging because it's 3v3 with 3 generators to defend.  At the beginning there are random weapon drops that fall from the sky with power weapons.  Rocket Launcher, Sniper Rifle and Spartan Laser are all available.  You will want to grab these because all of them can do massive damage to the generators.

Spartans

• Keep the generators locked down!  They only need to cool off for a couple seconds between lock downs, so keep them locked down.  Even if they're not being immediately attacked, they are vulnerable to quick ranged damage from rockets or laser if left unattended.
• Because there are only 3 Spartans to defend 3 generators, one Spartan should sprint off to each generator and lock it down.  The Spartan on B can then head over to A to help hold that one, as its the harder of the two outdoor ones.  Once A or C falls, one Spartan should stay near each one, with a runner between the two.  Once B is the last one left, everyone should fall back indoors.  Though the generator can take damage from outside, most players don't know that yet.  Also, staying indoors helps keep the generator locked down as much as possible.
• Watch out for friendly fire!  The generators CAN take damage from friendly fire.  Be careful of lobbing grenades at Elites near generators.

Elites

• Grab the power weapons!  Because the generators are vulnerable from range, you can do massive damage without risk if you're holding any of the power weapons.
• Grenade and melee!  These have the highest ROI of damage to the generators.  Some Elite loadouts give you 3 grenades, take advantage.
• Divide and conquer!  The Spartans can't be in two places at once, so if you see one generator lock down, that means another is likely vulnerable.

HR: Maps - Overlook

Overlook is the map that Network Test 1 (a.k.a. Generator Defense) is played on, the playlist that went live yesterday morning.  It is a medium sized, asymmetrical, outdoor map that pits Spartans against Elites.   Click for huge:

These are the locations you should be aware of:

1. Spartan Spawn - This is where the Spartans start.  There are a couple points to choose from, but they're all basically around this base.
2. Elite Spawn - This is where the Elites start.  Again, there are a couple points to choose from, but they're all basically below the river in this picture.  From the Elite spawn point, both Generators A and C are visible and hittable with ranged weapons.  Generator B can be hit from a perch on the hillside on the bottom right of this picture, reachable by jetpack from the spawn.
3. Generator A: This is the hardest one to get to from Spartan Spawn and generally the one that falls first.  It should still be defended to tick time off the clock.
4. Generator B: This is actually inside the Spartan base so is usually the last to fall.  Note that it can be hit from outside the base though, so Spartans will want to keep it continually locked down.
5. Generator C: This is easily accessible by Spartans from a number of paths and has a chaingun mounted nearby.
