I just got done taking Amazon Basin and I'm trying to tak Altiplano but every time I try to take it they have me in that transport for the Masari right next to the enemy base. Now I try to build a base right next to the enemy base but then the enemy just rushes me. Any help would be welcome.
What i would do is get a fleet with your hero, like if this is the mission i am thinking of, you are Masari, and as such you can get peace bringers. Have at least 3 of them in your fleet, id say 6 inquistors some some sky lords and disciples. Drop them off next to your opponets base and let them reak havoc.
For some reason I landed near the enemy base with SEVEN peacebringers (maxed out) in my fleet and I got my :):):) kicked by landing beside the enemy, fly to the southwestern flatlands and build a base there, wait for the enemy to do some rushes through the North AND some through the south-central crossing, capture the Hierarchy Outpost and hold it to scan with, let them rush a few times while teching/defending and then kick their :):):):):) (Sky Guardians recommended among Matter Engines to ward off Monoliths) after their first 3-walker rush
Skylord if you fly right up to the walker can destroy an Assembly walker arm in one, maybe two shots, and it will blast a Science Walker core to half health at point blank, use them if you want, It's a Peacebringer/Skylord combe that worked for me.
