Cheat Mode:
Finish the game at least once. Begin a new game, and
wait until the starting sequence ends. After Rain leaves, you and Hana can be
controlled for the first time, you should see a small control pad on the
left-hand wall immediately after the screen switches. Walk up to it and the
"Use" option should appear. Press Triangle and enter one of the following codes.
All Weapons:
At the small control pad enter
"11692".
Unlimited Ammunition:
At the small control pad enter
"61166" .
Big Head Mode:
At the small control pad enter "10397"
.
Concept Art:
On disk one, enter Left, Right, Up, Down, Down, Circle
on the title screen. The screen should flash red. Now you can access a library
of concept and development art (from the options, extras menu).
More Concept Art:
To get more concept art enter these codes at the
title screen on these disks
disk2- Up, Up, R1, R1, R1, Square. disk3- L1, R2, L1, R2, L1, Square. disk4- O, O, Square, L2, Square.
Walking the Walk:
In the later stages of the game, you’ll be forced
to deal with monsters that will appear out of nowhere. These creatures are
released by stepping in certain locations. You can train yourself to know the
areas and not trigger them, letting you pass almost unscathed.
The
Boss Tip:
When you’re tackling the end boss with Rain, keep toggling the
weapon and item select buttons between your three weapons. You’ll be able to
equip the required weapon quicker this way.
Pay
Attention:
There are a LOT of puzzles in Retro Helix that have their
solutions explained to you right before you do them, or the answers are on a
wall opposite the puzzle. Make sure you pay attention to everything in the game,
especially small details like wall hangings and verbal discussions, and never
skip a cinema.
