1. This is a timed mission. You have 17 minutes to break through the flood army and rescue the nearby marines.
2. Black Box Location: The second group you rescue is Bravo Team. The black box is next to them. Just make sure to pick it up.
3. Immediately build 2 supply pads.
4. Next create a reactor.
5. Upgrade your main base into a fortress. You can do this while your other buildings are in progress.
6. You'll need some defense. Go ahead and put towers in all 4 potential spots around your base.
7. When the reactor is complete, upgrade both of your supply pads.
8. Create a second reactor and then make a vehicle depot.
9. When your fortress finishes, build 1 more supply pad and a field armory. Since you are so low on time, don't bother with an air pad or barracks. It's better to just get the extra money and put them into tanks.

10. Start training scorpions at your vehicle depot. Make as many as you can.
11. Watch the timer. At around 14 minutes left, you'll automatically get an optional objective.
12. Optional Objective: Place Gremlin at Pylon
13. This optional objective isn't very optional. You'll need to do it if you want to complete the mission.
14. Also, you don't have to train the gremlin units, you'll get them for free. Just position them where the game tells you to.
15. New Unit: Gremlin
16. The gremlin is a special tank with a unique ability. It can send out an EMP blast to desable nearby tanks and buildings.
17. Move the gremlin to the pylon just North-East of your base. Once it reaches the destination, it automatically uses an EMP bomb.
18. Good news, that EMP bought you some time. You'll get an extra 4 minutes on the countdown.
19. Keep training scorpions. You can't have too many, so constantly be training more.
20. Once you have 5 scorpions, it's time to rescue Alpha Team. Take your army North-West to find a huge group of flood.
21. This battle is tough. And at this point you won't have had time to get canister shells yet.
22. Concentrate on the flood launchers first. These will tear your army up fast. Ignore the nearby swarm and just go straight for the launchers.

23. Once all 5 launchers are down, now it's time to get the nearby enemies. Try and focus fire on each little swarms one at a time.
24. You will lose scorpions here. Just keep training them at your base. It's possible replace lost tanks just as quickly as the flood can destroy them.
25. When you've killed the majority of the swarm, focus your attention on the flood den. This is the building that produces units. So take it out.
26. Optional Objective: Kill 350 Swarms
27. This is the objective that leads to the skull. You'll kill a lot of swarms normally, so worry about this later.
28. Save up some supplies and upgrade one of your reactors. Now you can research canister shells at your vehicle depot. Do it!
29. You've saved Alpha Team. A pelican flies in and picks up the remaining survivors. Fortunately, you also get a special reward. A grizzy tank joins your army!
30. Go slightly North-East to find the second pylon. Train a gremlin at your main base. Send it up to this pylon to recieve an extra 4 minutes on the timer.
31. Now it's time to save Bravo Team. If you travel West from where you rescued Alpha, you'll run straight into them.
32. Now that you have 3 power, create some wolverines. Train at least 3. These tanks specialize in anti-air and will be a big support for your scorpions.

33. Start the next attack while your wolverines are training. Your scorpions should be enough for now.
34. Use the same strategy here. Defeat the launchers first.
35. TIP: There is an easier way to defeat the swarm here. Press D-Pad Up and then select Cryo Bomb. This special ability freezes everything in a small radius. But it also does bonus damage against air units. This can devestate the flood army. But just be careful not to freeze your own tanks!
36. Once the swarm and launchers are down, turn your attention to the colony.
37. Alternate training wolverines and scorpions. By now you should have a ton of extra supplies.
38. With the colony down, a pelican automatically comes in and rescues Bravo team. Good work.
39. Upgrade all of the towers at your base. This can be done at the field armory. From this point, the flood won't just play defense. They'll attack your base every time you take your army out.
40. Now send your army North-East towards Charlie team.
41. When you reach the large flood infestation that's blocking Charlie, look South-East to find a small path. Take your army down this path while destroying the launchers here.
42. At the end of the path is the pylon. Train a gremlin and send it there to add some extra time to the clock.

43. Go ahead and train another gremlin. The final pylon isn't far away.
44. Send your army North. Kill all of the flood bulidings by Charlie to rescue them.
45. This battle is really easy. There are only a few launchers, so kill them with your canister shells. Now attack the nearby swarm. Compared to the last battle, this one is a breeze. A cutscene plays once you've cleared the area.
46. It seems that the pelican sent to rescue Charlie is down. You're mission isn't over yet, now you need to escort Charlie yoruself!
47. Send a gremlin just North-West of Charlie unit. Here is the last pylon. There are some launchers guarding it though. Destroy them and then place the final gremlin. When the EMP goes off, you'll earn the achievement The Procrastinator.
48. You should have plenty of time to get Charlie unit back to your base. Add them into your army and start heading South.
49. At this point you should be extremely close to killing 350 swarms. You won't need to farm enemies for this, you'll fight enough on your way back.
50. TIP: Once you reach 350 kills, the Catch Skull appears on the South-East section of the map. This is near the first pylon you used an EMP on. To get it you'll need a hornet. If both of your hornets died, create an airpad and train another.
51. Once you have the skull, just escort charlie team down to your base. Charlie team is already very strong by themselves, so this escort is easy.
52. The mission ends automatically once the majority of Charlie team reaches your base.
