letters fighting numbers?

They are all numbers (most of these are real irrational numbers represented with a symbol).

"Alpha"? Not quite familiar with the mathematical meaning. "E"? Yeah, I know that one. 2.71828 etc. The third one I'm unfamiliar with. I think the last one is a lower-case "Theta", but I could be mistaken.

Where's my "pi"!?

The Alpha is the second Feigenbaum constant (2.50290787509589282228390287321821578638127137672714...)

e is (2.71828182845904523536028747135266249775724709369995...)

Phi is the golden ratio (1.6180339887...)

Delta is the first Feigenbaum constant (4.66920160910299067185320382...)

The pi is just in front of you... (if you have a flat-screen, consider changing your angle of vision)

The place of the digits of the numbers have an effect in the battle (that's never explained, even if you look at the script it'll be very hard to understand completely)
