How to unlock the Eradicator achievement in Stormrise - Definitive Guide
2 make ai echelon
3 starting resources at max
4 start up the game and make 3 ships with your 3k resources
5 group ships
6 press select to locate enemy
7 fly ships over they will kill all units as easy ai do not make ships should take 5 minutes to destroy all bases minimum effort
Take your commander and try to rush one of the nodes near the enemy base. Build Stalkers if playing with Echelon otherwise build Matriarchs. Once you have that node you can route all enemy forces assaulting you and advance towards the primary node of the enemy.
Send out search and destroy teams if the enemy starts to capture additional nodes. He should not have many units left and by taking his primary node you can win matches in under 10 minutes if you know what you are doing. Not playing Echelon you will have an invulnerability shield on your hero so you can easily draw fire and win with less powerful units.
Note that there are 10 maps and not all maps allow you to build powerful units. Focus on fast units backed by a commander that can draw some fire as the AI will often focus him first on the maps where you face unit restrictions!
This strategy will have a map finished in 4-10 minutes depending on the size of the map (my fastest was 4 minutes).
Set the AI's on easy, Energy High
Hit x to change your team to Echelon which is a arrow pointing down. Enemy doesn't matter, just build 3 Hunters (aircrafts). Capture the first 2 nodes near your base going towards the enemy's base (use Back button to see the map, enemy's base will be red). Just send your Hunters and kill the enemy's Hero right away, then attack all the other units. After the first 2 nodes are captured make them into refineries. Then send your hero over there and kill everything, take bases along the way if possible. You have power over the map by using the Hunters.
Don't forget to use the Hunters abilities like Rocket Barrage or Fly low if needed, by using LT and using right analog stick to hover the ability.
The Map won't end for me why is this?
You must kill all units, don't block the enemy's base with your hero or they won't spawn the last of what they got. Just sit back and only let your Hunters hover over the enemy's base.
Skirmish is a mode which lets you play battles in the same way as you would in multiplayer, versus one or more AI. For this trophy you will have to beat the AI on the 10 maps the game has to offer. Note that you can set the AI on easy for this trophy.
A very simple way is to build 3 hunters right at the beginning (don't forget to set high starting resources in the settings to do so), regroup them and make them rush towards the main enemy camp; you can bring your fully equipped commander at the same time, giving him indirect orders ( press on his icon + for direction). The AI always has the same strategy/pattern: it takes its commander to the closest node to capture it then spawns some troops in their main camp. Destroy his troops first (3 hunter units can destroy almost anything) and the commander will fall back to your direction. If he doesn't, look at the map (by pressing ) to see which node he went to. The AI will probably spawn more troops until he has no more resources, you will have to destroy them too in order to defeat the AI. On average, this method takes 3-4 minutes per map so you should be done in less than an hour.
The AI on the easiest difficulty is very easy to beat. Just play a skirmish on every map against an easy AI and this will pop in no time. Save up for heavy units, such as the Matriarch. Advanced strategies and tactics aren't really required against easy AI, just use brute force and you will overcome them in no time. Another method is to use an air rush, targeting nodes so that the AI cannot gain resources. Set the game resources to high and constantly spam dragons/choppers whilst upgrading your own nodes.
