Halo Wars: Definitive Edition

A fun easy mission(even on Legendary), that is basically a tutorial mission for part of it.

My strategy for Mission 2: Relic Approach

The overall focus in order of importance:
1. Build up your base
2. Protect your base from Covenant Airdrops and train lots of Scorpions
3. Take the 2nd base, build it up
4. And either take the objective or do the bonus objectives first

My general walkthrough steps:
1. You will be forced to do certain steps at the start as part of the base building 'tutorial'.
2. Once you have free control, build up your base, and make sure to get 4 Turrets with Anti-air upgrades.
3. I'd recommend at least 2 more supply pads, and another Reactor to get a Vehicle Depot.
4. Covenant will be sending in dropships with troops right in front of your base--if your Turrets can't take them out, then make sure to leave some troops nearby to help out!
5. Alternatively, you can take Forge and a Scorpion out the left side of the base, go North, and you can take out the Covenant Refineries to stop the Covenant Dropship attacks.
6. Once you have at least 5 Scorpions, move out and start knocking out the Covenant positions to the North.
7. Move up the map to the North, and take out the Covenant base. There will be a lot of Hunters defending, so it might be a good idea to have some Marines in between your Scorpions and the Hunters.
8. Once you knock out the Covenant base, build your own with Turrets, and then either go straight for the objective or do the bonus objectives around the map.
9. Don't forget you need Marines to walk through the barriers, so don't accidentally max your population with tanks and have no Marines to walk through the shield barriers!

Have fun on this mission! It can be challenging in parts, but is quite fun also.
