How to play Starcraft Master mod

Put the one Marine that isn't attacked on Hold Position. Run in circles with the other. If you don't make sharp turns, you won't get hit a single time.

Your stalkers are faster than the Zealots. Just studderstep them: Run a bit until you have a small gap. Press Stop. Let them shoot. Repeat until win.

Run all your Zealots back to the smaller choke immediately. Put them all on Hold Position when arrived. They should form a nice line. One Zealot will not be able to attack at first. Replace a weaker one with him, when needed.

Wait until the Marines go north. Burrow all your Lings in their pass. When the Marines are exactly above your lings unburrow. Lean back and watch.

Split the hydras in two groups. Queue a move command for the left group to go slightly to the left, the other slightly to the right, so that you get a nice arc as soon as the challenge starts. Move weak hydras back to mitigate damage.

Targetfire the spinecrawler. Move back weak hydras. The spine may attack a hydra 3 times before you have to move it back.

Put the colossus on hold right at the beginning. Wait until ALL the lings come to the highground, then go down the cliff and hold again. Repeat. Important: Wait until ALL lings are either on the low or high ground. If they get split up, you might be in trouble. Also make sure that your Colossus never stands half on the high and half on the low ground.

Blink up to a tank so that you stand really close. Take him out, then walk real close to the other tank. You can spread your Stalkers out a bit, while attacking the first tank, so that the other wont splash-hit both, but thats optional.

Attack the bunker. Burrow weak roaches, thus mitigate the damage over all three. If necessary you can burrow all 3 roaches for healing as there is no detection.

Go to the most southern end of the platform with all your units. As the lings attack, close the cap with 3(!) ForceFields. That should be enough, to not get hit by a single zerling. Replace ForceFields right before they expire. Let your units just autofire. If the FFields land correctly, you wont lose a single bit of healthpoints.

This challenge is bs. You need to walk your HT back as soon as the challenge starts. Then you need to attract attention of very small groups of marines, by baiting them as you walk close. If you are lucky, you get chunks of 3-6 marines, if not you get a single marine. Repeat this until every marine is dead. Can take up to an hour or so.

Send your drones mining and build an overlord asap. Larva will pop out very quickly. Build 3 drones, as soon as overlord pops. When the 'rush' comes, wait until the lings are in the mineralline, then select all workers and a-click somewhere. You even may build 3 more drones, but thats optional.

Queue a probe in the nexus before the challenge starts. Take all your probes, right click asap on the cannon and put them to hold position. This way you will get a nice surround on your cannon. Correct the positioning a little bit, so that there is a full blockade on the cannon and no zergling can slip through. Because the lings are set to targetfire the cannon, they won't attack your probes, if they are on hold. If the cannon has exactly 8 kills, you can a-move all your probes to get a nice completion time (my record: 27.5 seconds).

Move all your Zealots away from the lings at first. Then select single zealots and attack-move them into the banelings one by one. Spread the remaining zealots out, and put them on hold. You may ensure your victory by grabbing one zealot and movecommanding him with some waypoints along the edges to place the banelings initially spawend.

Before the challenge actually starts, grab the left 3 hellions and set them to target fire the 2nd left marine in the 2nd row. Tell the 2 other hellions on the right to target fire the 2nd right marine in the 2nd row. In fact you can lean back now, while the challenge is actually going on. If for some reason that doesn't work for you, set all your hellions to targetfire a marine in the middle AFTER they blew of their first shot.

If you put the unfocused marine on hold position you are required to run in small circles with the other marine in order to be shooting the zealot with the unfocused marine all time. However, as you already pointed out, small circles means that the zealot may deal damage or even kill the running marine. So, don't put the marine on hold pos, run in bigger circles and switch the marines' roles should the zealot change focus. To complete the challenge a few seconds faster start shooting with both marines when the zealot is low.

Pressing stop to do the stutter-step doesn't ensure focus firing. If you want to do the challenge faster press attack on one of the zealots and focus him (of course still stutter-stepping, just with a-move instead of stop-command). As soon as only one zealot is left you may repeat the process of the first challenge, letting the running stalker shoot from time to time. Let's you complete the challenge faster. You may also just stand still with both stalkers for the last zealot and let him poke away. Shields will deplete, no stalker should die though.

Run your zealots back to the fan instead of blocking the broader passageway. There even is a small gap between map-border and fan, which allows you to neatly tuck away one zealot. Screenshots: http://i.imgur.com/NdROJ.jpg & http://i.imgur.com/vvjrO.jpg

The trick is to position the burrowed zerglings in a way that makes the marine ball disperse, allowing all of your lings to attack and surround single marines. If your burrow is positioned well enough you may sit back. If the ball remains dense you will fail.

You can blink your stalkers right between the tanks. There's a small spot where both of the tanks cannot shoot and your stalkers will take zero damage. Finding the right spot is easier with just one stalker, so feel free to leave one of the stalkers behind where the tanks can't reach and eventually call it in when you found the spot with the first stalker.

Burrow the weak roach. Make sure the bunker changed focus and unburrow it again for additional firepower. As soon as the next roach is low, burrow both the earlier weak roach and the current one. Wait for the bunker to focus the healthy one and unburrow again. When the last roach is low burrow all, wait a few seconds and unburrow the healthiest first, quickly unburrowing the other ones. Repeat from beginning for profit.

Don't build an overlord. The overlord will pop the second the lings run in, so the additional drones you produce will come in too late (assuming you actually need them). A better way is to do a double-extractor trick to quickly free up supply. When the lings run in select all your drones and send them to one mineral patch. As soon as they are clumped, do the a-move and your drones will automatically spread. With a little bit of micro you can keep weak drones alive by selecting them and putting them on hold position (cancelling the attack-command and making the ling that is attacking them change focus). After the ling stopped attacking the drone you can put it on a-move again.

In fact the zerglings will take out one or two probes to get to the cannon. It's nothing of importance though. The cannon should be able to cope with one ling attacking it.

There are several possibilities to do the challenge. One is to do a little bit of scoot-n-shoot with the hellions. Everytime the hellions move back the marines should clump up a little, allowing your splash to have more effect. You also may take 2 hellions of your main group (that is attacking from the front) and run them to the sides and abuse the concave the marines form.
