What happens if you remove randomness from Doom?

For some reason, recently I have been thinking about Doom. This evening I was wanting to explore some behaviour in an old version of Doom and to do so, I hex-edited the binary and replaced the random number lookup table with static values.

Rather than consume system randomness, Doom has a fixed 256-value random number table from which numbers are pulled by aspects of the game logic. By replacing the whole table with a constant value, you essentially make the game entirely deterministic.


Pez:

Very nice read. I love how people are still discovering new things about these old games. I find it interesting how much the monster behavior is based on the random number table.
