要越墙，如果不能越墙，我在下面复制了视频作者的评论，懒得翻译了，随便看看吧：

For a good start I suggest
1. Salvage the two bunkers close to each other, near your base
2. Immediately queue up SCV's, set rally point of command center at mineral nodes and use one SCV to build a refinery
3. Keep SCV's queued up, your aim is 3 SCV's per mineral node and 3 per refinery
4. Bunker up marines and build one tech lab and one research lab per barrack
5. Assign one SCV to keep building supply bunkers
6. Assign an SCV each to build a bunker at the East and West entrance to your base, you want to fill these up with marines asap and it's recommended to assign a group to each SCV for easy repairs to each bunker
7. Build a third barracks and upgrade to the one which allows you a second build queue. Keep pumping out marines and medics the entire game roughly at a ratio of 5:1
8. Research both upgrades before you have a sizable force ready to leave
9. Use A + click for attack move, get your army to attack the two very north hatcheries but DO NOT kill the zerg worker drones (ignore the part in this video where I did attack them)
10. Hide your army till the hatcheries are getting rebuild then attack again and you should have destroyed 4 hatcheries total
11. While this is happening you must keep an eye on your base and keep building units/ supply building
12. A third bunker on each entrance will also make defending very easy as Zerg tries to attack buildings first and infantry units second.
13. Keep your medics behind your marines
14. Good luck

哦，看了一下，窍门是用你的mm组合攻击北面的两个hatcheries，不要攻击drone，然后把部队拉开，等电脑重建hatchery，建好后再摧毁之，这样你就达成了摧毁4个的目标。其他的爆兵之类的就不冗述了。
