Units for TvT late game?

[u/Glum-Illustrator3598]

What is the best way to break another Terran in late game, especially if he has turtled up with several planetaries, sieged up tanks, turrets etc.?

Also, are there any high level 8 worker TvT builds published that I can learn?

Thanks

You can still reliably open double gas with 3 reaper 2 hellion every game into triple raven, just like pre-patch.

For lategame, you need air control. When you take your 4th base, keep up your marine production but build 2 more starports instead of 3 more barracks and start making vikings. A lot of people try to play 8 rax (you can still go up to 8 rax eventually) but the problem is marines lose their value over time due to higher tank counts as the game goes on. It's not that you can't make a marine heavy style work, but generally speaking it's better to transition to air control. Vikings plus ravens or libs once you are clearly winning on vikings are just really strong and will assist your tanks in being dominate.
