To earn this, you only need to complete the last level of the campaign, "6 The Storm". Select the S-104 Dart. It is the fastest ship and its weapon can pass through ice. Additionally its weapons shoot farther than the others. Keep [Forward] held for a few seconds to move in hyperspeed through the first half of the level without entering any fights. After reaching about 50% of the level, the number of enemies gets lower. Begin fighting them at this point. After you leave the passage where you see ice at the top and bottom of the screen, fly to the top and enter hyperspeed again until you reach the two cannon towers in front of the large alien ship. When you slow down, notice that some enemies will still be following you. Kill them before you move forward. Go through the spinning gates. For the first one, enter then clear it from inside. The second and third can be cleared from the outside. When you reach the "core", get between the debris left by the last two cannon towers so that you cannot actually see the "core" yet. Begin firing and after you break the circle of the "core", that the health bar begins to decrease slowly. You will also hear the hitting sound for successful shots.

Play the survival level, "3 The Lighthouse" under the Tourist difficulty setting. Clear out almost all of the first wave but leave the pirate ship alone. It is very slow and will chase you. Fly to the end of the level and destroy the mines. When the pirate ship reaches you, turn around and fly to the other side. Repeat the process until fifteen minutes have elapsed.

Play the campaign level, "6 The Storm". Begin the level and do nothing. There will be no enemies. The difficulty setting and ship you select makes no difference.

This requires ramming enemies to destroy them, preferably with your shield to minimize damage. Select the "Tourist" difficulty setting and start the first mission in Campaign mode, "Pilot". Choose the Mule ship because it has the highest armor. After you shoot the mines at the start of the mission, a small number of ships will appear to the left and right. Fly through them without shooting. You should be able to take down all ships on one side and still have about 20% to 30% health remaining. You can either continue ramming until you die, then use the temporary invincibility when you respawn to quickly ram more ships; or ram a few more ships until you are almost dead, then heal by collecting the green wrench symbol blocks or scoring points. When your health is full again, resume ramming and repeat the process.

• Start Survival mode in Ice Canyon. Select the faster bee-like ship and fly against the first ice wall you encounter, slightly to the right.

• In the first level of Campaign mode, select the Pilot difficulty setting and Overseer ship, which has good speed but poor armor. Then, move into the mines.

You must rank in the top 15% on the leaderboard for this mission. Select the Pure difficulty setting in order to get the highest multiplier. Play the survival level, "1 Last Line of Defense". Select a ship with decent speed for this mission due to the numerous amount of fast enemies. You will start in the center of the map. Start by flying to the right and killing the first row of enemies there. Then, turn around and fly to the left and do the same thing. Repeat this the entire time and try to avoid any damage. This pattern will help ensure that nothing kills you from behind. After up to ten minutes, you should earn about 30,000 points. Combined with the multiplier from the Pure difficulty setting, this should be enough to earn "Immortal (kind of)".

You must rank in the top 15% on the leaderboard for this mission. Select the Pure difficulty setting in order to get the highest multiplier. Play the survival level, "2 Ice Canyon". Select the S-116 Wasp. Reach the Cyclops until the four minutes run out. Because he is the only enemy, use the special fire button about three times and he should be almost destroyed. Afterwards, fly back and collect all the extra points remaining on the way.
