Periodically, a cargo pod (looks like an egg with propulsion thrusters) appears coming down from the top of the
screen. Destroying it will release 5 medals. However, if you let the cargo
pod live long enough to try to escape to the top of the screen, and then
shoot it as it's moving up, it will release 10 medals.
This trick is similar to Raiden DX's
medal trick, and it is available in Viper Phase 1: New Version only. There
are two types of medals in VP1, 500-pointers and 1000-pointers. After a
while the medals will stop shimmering for a brief moment. If you can grab
the medal at the moment it's not shimmering, you'll be awarded extra points.
The medals will be worth 2000 and 3000 points respectively.
Destroying all the storage tanks in
Stage 4 will give you a 40,000-point bonus.
Destroying a formation of the flying
spheres in Stage 4 is worth 1,000 bonus points. Each additional consecutive
formation you destroy will increase the bonus by 1,000 points all the way
up to 10,000 points. Missing just one sphere in one formation will reset
the bonus index back to 1,000 points.
