So what you want to do is build a factory of your choice :D then build some fabricators like (2 recommended) and a scout if you want to find out your enemys location then build walls around every entrance/exit you have! the size of the base needs to be big obviously like this

in the pic i already have everything down tho then build a adv factory to build your holkins once your factory is finished make it build 2 fabricators while your tier 1 fabricators build some energy plants or pelters to support the holkins that soon will be built by your tier 2 fabricators. also dont forget to use adv radars to help your holkins and pelters shoot

So once you got atleast 3 holkins down with extra pelters to support the enemy or ai might try attack but the pelters and holkins will fire at the army before they reach you as the adv radar helps holkins attack anything within its radius unless you got no energy to power the radar.
so then you want to expand to the next area make sure to build walls and put turrets and AA turrets with them.
as you can see in the screenshot i have a few holkins closer to the enemy base so that way they can attack more units before it kills you which is good! never stop expanding and putting defenses down till you have holkins shooting at the enemys base!

You could also expand to space and get lots of metal and energy off gas planets if there is any also use the solar panel units in orbit it helps with energy ! just defend them tho

once you got your holkins able to fire at the enemys commander you can start to build up a army of units of your choice as their commander might move out the way and stay safe which no one wants unless its you dying from the True Turtle flavoured Tic tac (Tac-tics... get it? :D ) and then swarm the enemy with your units and destroy them! although you might be like 40 or 50 mins into the game you will win regardless unless the enemy rushs you with air units so fast that you cant get any AA guns up to defend...
in this screenshot you can see me destroying the enemy with holkins!
heres another pic of how i put the holkins to destroy the enemy

Normal turtle tactics involve max pelters and the minium or watever of holkins and lots of units to defend

Technicly a quick defense solution incase True turtle isnt possible in the game your in but it still works great!

1: Use air units to defend agaisnt air units

2: This Tic tac is great for the sea too!

3: Oribtal only for defense or gas planets

Hopefully you have found ways to improve this Tic tac tactic if you have then please display them in the comment section any feedback too
i already know some of the flaws like it takes to long and your vulnerable sometimes but thats why you put walls down with turrets behind them then AA turrets behind those
always use adv radars to get as much dmg done and such!

:D
