2 hidden easter eggs in the Thalion intro. These will work once the Thalion logo is on screen:
1. typing "aaarrgh" (without quotes) will switch tunes. Typing it again will restart the new tune.
2. typing "schnism" (without quotes) will make the Thalion logo bounce up and down.
Accessing "the hidden juke-box":
During gameplay, you can type "jochen was here" (without quotes). This will take you to a hidden juke-box, which let's you play almost all the tunes of the game.
If the code does not seem to work at first, be sure to type one letter at a time (with a short pause between each key press).
Using the built-in cheats:
During gameplay, press and hold, one at a time, Left SHIFT, Right SHIFT, H.
Release those three in reverse order. In other words, release H, then Right SHIFT and then Left SHIFT.
A brief green flash will occur.
The instant the last key (Left SHIFT) is released a timer is started: you have about half a second to press the F5 key.
If done correctly, a pale blue flash will be seen.
This will grant you infinite lives.
Additionally, You can then use one of the following:
Cursor up: Advance one level
Cursor down: Goes back one level
W: Takes you to the end of level warp tunnel
Left ALT: "free subjects from the Myrons". This seems to be a smart bomb of sorts. After clearing the screen of flying enemies, no further attacks should come from the air. Also, destroying any one power station let's you immediately go to the anti-warp generator portion. (good for level 6 which has 25 power stations)
T: Goes to the end of game sequence if you are using the release included in the Thalion: The First Year compilation (SPS release #3054).
If you are using the normal version of the game (SPS release #3053), you will directly be taken back to the starting screen (without the end of game sequence).
Pressing HELP produces a red flash and turns cheat off or resets keys if you were too slow hitting F5.
