Halo: Spartan Assault

The objective of this mission is to find and kill the Elite Generals scattered around the map. This map is very large, and there are plenty of vehicles around to use and/or hijack, but for this achievement, you will NOT want to get into any vehicle.

I personally recommend purchasing a Sniper Rifle and the Rocket Launcher for this mission. The former weapon will help take out ground troops – Elite Generals includes – very easily, while the latter weapon will dispose of the Covenant Wraiths, Ghosts, and Shade Turrets that populate the map.

Also, once the Drones spawn, they do so in countless waves that never seem to end. You may ned to swap one of your weapons out for an automatic rifle to get rid of them quickly. Overall, keep trotting down the canyon, killing all six Elite Generals and do not step into any vehicle! Once the last General has been taken out, the mission will end and the achievement will be unlocked.

This mission is a rather wide open area full of tons of turrets and vehicles (Ghosts and Wraiths), but with your setup it's not all that difficult to run through it.

Basically, you want to rely on using your hologram to distract enemies, allowing you to run the opposite direction. Using this effectively can reduce the fire you take substantially, and also help influence the many Wraiths to help you thin out the numbers via friendly fire. The main idea for this achievement is to just run from Officer to Officer (the objective targets) and take them out, then move to the next. I found the Needler available in a crate near the very first ghost to be satisfactory for this, but obviously doing it with the Sniper Rifle will be even easier since they'll only take a single shot to kill. There aren't a ton of grenades in this level, so be sure to use them primarily on the Wraiths>Tanks>Turrets, since that's the general order of threat. Overall, it's a pretty simple achievement, though you most likely won't get the gold on this run.
