Cutthroat (Achievements) | Campaign - Rebellion missions SC II: WoL Guide
Last update: 11 May 2016
Cutthroat:
Buy Merc Contract Before Orlan, Destroy Orlan's Mercenary Forces.
Minesweeper:
You can begin planting the mines at the very beginning, using them to secure your camp. If you have to, you can continue placing them after paying for the mercenaries, just at Han's encampment. Don't attack Orlan until you get a message telling you've completed the achievement.
Solitaire:
Above all, you have to quickly get rid of Orlan's three encampments, as thanks to them he's gathering minerals much faster than you. Get every worker you have to collect crystals, ignoring all else for now. Get one to build a bunker for the Marines on the southern side and wait for Han to send you the Vultures. They're the strategic units here.
Mine both camp entrances. Buy a full round of new Vultures and go for the northern base without waiting for them. While attacking the colonel's forces try not to attack a single unit with all your Vultures at once. Reloading does take some time and a Marine falls down after two or so shots. After clearing out this area, repair your Vultures at the base and pace a second bunker, this time from the northern entrance. Place some new mines as well.
Strengthen with new Vultures, attack the other two enemy bases. If you have problems with the Goliaths or the large number of Marines, try to attack by surprise and then quickly retreat. This method will allow you to limit the losses and confuse the enemy a bit. Alternatively, once you see a large enemy group, you can plant mines, wait for them to arm and force the enemies to come their way.
In the meantime you should place new mines around the base, as Orlan's attacks will intensify as you play through the mission (Siege Tanks will appear, for example). Of course don't forget to collect the scrap metal while you explore the plant, which should boost your earnings drastically. You complete the achievement after paying the mercenaries. You can use the SCVs.
