Halo Wars: Definitive Edition

The intro mission to a terrific RTS! Legendary can be tough.

My strategy for Mission 1: Alpha Base

The overall focus in order of importance:
1. Keep your units alive!
2. Avoid firefights if you can, rush through the level.
3. Use the Warthogs ram ability as often as you can.
4. And of course, your Marines grenade ability!

My general walkthrough steps:
1. You start with only Forge. Go full speed ahead, and have him help in the first battle by running over some Elites as well as blasting them down.
2. Take your new Warthog, select all units with , and rush down the pathway. Ignore the scattered grunts, drive past them all, and go around the next couple turns until you see a large battle ahead.
3. Rush Forge and your other Warthog into the battle to run over as many enemies as you can, then back them out so they don't get too damaged. Have Forge use his Gauss cannon in between rams.
4. Take your 4 Warthogs, and rush ahead, ignore any enemies, although do target the Ghost with all your Warthogs, then rush ahead to the next battle. Ram enemies and take out the Turret as soon as possible.
5. Proceed ahead, run over more enemies, and then call all your troops to the door. Consider using your Leader Heal Power if your troops aren't looking very healthy. To do so, press and select it with your joysticks and .
6. Walk some Marines through the Shield door, have them grenade the power generator, then assault the base!
7. Try to be careful, use your Marines grenades and your Warthogs ram as much as you can, and Forge's Gauss cannon absolutely wrecks the Covenant.
8. Carefully attack, and push through the base; soon you'll take them all out or die trying!
9. If you do die here, then revise your tactics, try to use more mass attacks on the Covenant in the base, and keep your Warthogs out of the action until they can ram.
