Secrets (Shadow)

From Sonic - Wiki on Neoseeker

[edit] Misc. Secrets

Shadow The Hedgehog has a number of secrets for the committed player to unlock...

Extra Weapons
Complete the game following any "6-X" Level which you have not already completed, and complete either Mission. You will receive the new weapon upon defeating the Boss.

Level 2 Extra Weapons
Do the same as above, but complete the other Mission in the "6-X" Level to unlock the Level 2 upgrade for your Extra Weapons.

Shadow Rifle
To unlock the powerful Shadow Rifle, complete the Last Story.

Expert Mode
Expert Mode can be unlocked by obtaining a top rank on every Mission of every Level in the game. This mode puts you up against a harder version of one Mission on all of the Levels, with no Bosses.

[edit] Cameo and References

Shadow The Hedgehog, despite its new image, isn't afraid to make a few brief references to other Series'. Here are all the ones we've found so far...

Yugi Naka
Yugi Naka, famous creator of Sonic, has a cameo role in this game as an innocent civilian. During the Black Arms invasion of Central City, standing around a group of human, non-attacking G.U.N. Troopers can result in one of them saying into his communicators, "Mr. Yugi Naka is safe!".

[edit] Trivia

It is the first game in the Sonic Series to feature the entire Sonic X vocal cast.

Dr. Eggman is the only character in the game who is the protagonist of both Hero and Dark missions.
