From the main menu, select Snapshots, Snapshot Playlists and go to "
Blast Score". You'll now need to complete all 5 snapshots without losing a life:
1 - Hold
to fire, and slowly move back and forth occasionally moving your aim up to hit additional enemies.
2 - For Battletoads, go up to enemies and tap
to hit them and kill them. Kill 3 enemies to reach the goal.
3 - This Cobra Triangle can be a little tricky. You will be automatically moved forward due to water current and you must hit the enemies on the side of the shore. Each enemy is worth 100 points, but every consecutive enemy, you get an extra 50, so the key is kill a lot of enemies in a row without missing.
4 - In Snake Rattle N Roll, just grab the first "Y" pieces and then grab the black circle with your tongue. The only thing you have to worry about is hitting an enemy or getting killed by the crocodile in the water.
5 - From the start, go to the right hand side until you end up in a room where 2 skeletons spawn. Alternate between them and kill them as they keep respawning. Be as quick as possible, and kill 13 skeletons to reach the goal score.
If you're able to complete the playlist without losing a single life, the achievement will unlock.
