Just a glitch in the Matrix
Hi Johnny, thank you very much for trying my campaign!

Now let's see how to beat that nasty mission.
Ignore the various playthroughs on YouTube. None of them undertook this scenario in the way it should be played, and most of them managed to win by sheer luck, or because they have super-human micromanaging skills. I've even seen people lifting their buildings in order to use them as blockades, none of which will work. I guess that the reason you are always defeated is because you can't adequately defend the main gate (the entrance with two Bunkers), so we'll focus our attention on that particular spot.
- Upgrades are fundamental. In this mission it's very easy to forget to upgrade your units, since your attention is constantly brought to the Bunkers. Infantry weapons upgrades are especially important, whereas you can neglect infantry armor. You can't beat this mission if you don't reach level 3 for infantry weapons in due time, so always remember to check your Engineering Bay (you might want to hotkey it). Vehicles upgrades are important too, but not as much as infantry upgrades. Needless to say, you must also immediately research U-238 Shells.
- The best position for your hero Tank is exactly
between the two Bunkers at the main gate. Keep it in normal mode, since in siege mode the splash damage could inadvertently damage your Bunkers. Later on in the mission, when groups of Ultralisks will appear, you can briefly switch it to siege mode, but make sure to aim at distant units to avoid damaging your Bunkers. When in doubt, just leave the Tank in normal mode: it will still deal a lot of damage.
- Elite Firebats can be stimpacked many times, and they are devastating in stimpack mode (especially when upgraded). If a large wave is approaching and you are quick, you can unload the Elite Firebats from the Bunkers, stimpack them, and put them back inside. This is not necessarily needed, however, and I rarely do it.
- Slowing down the game speed is fine,
as long as you don't push it to be absolute minimum: in that case, the spawning triggers won't be able to keep up with the game speed, producing the annoying placement errors you reported. This is aggravated by the fact that many of those spawning triggers make use of the Wait function.
- I assume that you always have at least one SCV close to each Bunker, for repairing. Concerning the two Bunkers at the main gate, one SCV will not be sufficient, so I suggest you to have 2 SCVs per Bunker there: they will fix any damage very quickly, both to your Bunkers and your hero Tank.
- Apart from the Marines and Firebats loaded into the Bunkers, you also need many Marines immediately behind them, and also some Goliaths to counter Mutalisks. Five/six Marines might be enough to defend the two small side entrances, but the Main gate will be subject to much stronger attacks: you will need at least 25-30 tightly packed Marines there, along with a handful of Goliaths.
- Use the walls of the main gate at your advantage, making sure to place some Marines up there too. They will deal additional damage to the Zerglings rushing beneath, while receiving minimum damage from the Hydralisks. Consequently, those Hydralisks which are hit by the Marines on high ground will be distracted for a while, allowing the rest of your defenders to kill them.
- Don't be excessively scared by the occasional Infested Terrans: their damage is greatly reduced (200 instead of 500).
- Make sure the version you are playing is post 2020. The original version from 2015 featured standard Bunkers, whereas in the updated versions the Bunkers have additional armor.
- Don't underestimate resource gathering: even though this isn't a macro mission, you still need a constant income, or you might be unable to research those critical weapon upgrades at the right time.
- Obvious suggestion: save often. I'd suggest you to save your game every 3-4 minutes. If something unexpected happens, you can retry and you will be prepared.
I hope these hints will help you beat Mission 4 and proceed with the rest of the campaign. If not, let me know.
