Description
0:00 Freeze carrier build and Apoc - [LV.60 orange + yellow skirmish] 2:57 Cobra - [LV.60 Cloud duel] 5:23 Turret rush - [LV.61 orange duel] 6:27 Beam build - [LV.63 red duel] 9:12 Turret rush - [LV.63 Infest duel] 9:49 General defensive build [LV.64 green + Cloud skirmish] 11:51 Freeze carrier build + biolab [LV.64 red duel]

Beam build (beam-halo + 4 beam docs) is the most efficient around level 15-50 from my experience. AI beyond 60 just get a little too overwhelming. All AI can get multiple caps before you do, so I have to resort to cheaper carrier builds or economy build.

AI comment:

Red: Best counter: Beam build I think any other builds can kill them. They're easy compared to other colors. Slow non-homing projectile / carrier builds might have some trouble due to pesky pumas flying behind your base.

Green Best counter: Beam build SD carrier + plasma mastery also works but not quite well. Their maxed-out base is an insanity. Rapier legion + spartan tear apart everything. Try to kill them before that happen.

Yellow Best counter: Beam build Their focus on phalanx can be super-annoying, requiring a very different strategy from other AIs. They really limit my choice of armory for campaign. Luckily beam build ignore phalanx and is very effective. Another choice is to use freeze weapon + black hole/biolab

Purple Best counter: Carrier build Swarm from the carrier can distract those artillery very well. NY Grendel almost always able to push the HH back to their base. Actually carrier build aren't so effective either but it's better my other builds. At high level, the enemy can usually push back my fleet and I need to resort to apoc.

Orange Best counter: Carrier build (freeze + biolab) Freeze carrier is amazing at freeze-locking the enemy fleet. However they just don't have enough firepower and I usually got multiple frozen Goliath drift past my base. Biolab can remedy this problem perfectly. Sometimes it can create a large alien fleet.

Infest Best counter: Turret rush, Beam build This can be another troublesome AI since they can get caps out very fast. I use few microlasers + void lance + phalanx to hold them back (still a bit risky). It's very important that you have insurance on your void lance so you can sell it and mount your offensive as soon as possible. Beam halo is incredibly effective against them.

Cloud Best counter: Cobra or black hole If they manage to get caps before you get your cobra, just put a void lance + some turrets and there won't be a problem. Shield is actually the most beneficial mod on cobra when it come to fighting clouds. Unshielded cobra usually ending up getting freeze-locked after leaving the base.

Always carry an apoc with you when at high levels. It will help you a lot especially flank against purple or green.

Yellow/Purple/Cloud/Infest are easier to defend. You can even survive against their maxed-out base.
