 Sure Shot (10 points)
Defeated a wave of invaders without missing a shot.
When there is a small wave to shoot at just take it slow and easy. Alternatively, get a laser in one wave and hold it until the next wave and release it and get all of the wave with the one shot.
 Combo Meal (10 points)

This will come naturally, but if you're struggling get a blue or green Power-Up for a laser or broadshot and shoot from one end of wave till other.

 Hero of Nagoya (25 points)
Achieved 1 ROW using the Nagoya Attack technique.
A "1 Row" is where clear just one row without hitting anything else.
This is best done on Stage One right at the start. On the first wave take out all but the top row. If you hit one on the top row, restart.

Now let the last row come down the screen until a message appears saying Nagoya Attack, now finish off the row quickly.

Just watch the start to see the Nagoya Attack Method. Its easier to clear all but the top row so you don't mess up.

 Space Commander Rank S (25 points)
Achieved Rank S 3 times.

Watch this video. Once you have done this three times the achievement will unlock.

 Take That! (30 points)
Defeated a Boss Invader without missing a shot.
Start up stage one. Get to the boss then fire once at the yellow bomb ships and let them blow up, then carefully fire a single shot at the boss.  Keep doing single shots at the boss until yellow bombs appear again and repeat until he's dead. Just remember that you're aiming for the weak spot near the top. Be very careful not to shoot through the boss as parts you've already hit go grey. Hitting the yellow bombs does not count as a miss, but shooting through the boss will count as a miss.
