1. PATCH DESCRIPTION

This patch repairs and restores the original final boss fight of Illusion of Gaia: an intense, challenging, ludicrously fun battle against an apocalyptic demon comet.

Apocalypse Gaia appears after the regular Comet and Dark Gaia fights. Bring some herbs -- you'll need them. If you die to Apocalypse Gaia, any herbs you've used are refunded.

The code for this fight is in the game's ROM in a very early proof-of-concept state. It's full of bugs and slowdowns, never playtested, and relies on engine features that didn't make it to release. Like many other unused features and mechanics in the game, this boss was probably cut due to constraints on budget, time, and scope.

This patch includes bug fixes, engine improvements, and gameplay modifications based on playtester input, to deliver what I think the fight would have become if not for those constraints. My design goal in restoring it has been to reproduce the developers' intent, then tune that based on gameplay necessities and playtester input (which the developers did not have). That means that with few exceptions, the mechanics you see in this patch are either as-originally-coded, or a reasonable modification that would have been made later in development. I did, however, have to re-write the code (and parts of the IOG engine) to get it to run without slowdown.

4. TIPS


This isn't a kaizo hack.

The fight definitely looks hard, maybe even unfair. In reality it's active, challenging, and above all, new -- so it's expected that you'll die a lot while figuring out a strategy. Like the other bosses in the game, this one becomes a lot more manageable once you understand and adapt to it.

With that in mind, if you're struggling, frustrated, and don't know what you're doing wrong, here are some suggestions.

1. You're still playing Illusion of Gaia. Boss behaviors are scripted, scheduled, and telegraphed, with very few random elements and practically no cheap shots. Apocalypse Gaia might be all over the place, but it's still following a set pattern with set timings.

2. All green homing projectiles can be blocked.

3. The Aura provides free invulnerability longer than any of the boss's attacks, and can be chained endlessly.

4. Take it slow. There's no time limit, and the boss isn't going anywhere. The mechanics of the fight reward a cautious approach.

5. Spoilers: If the above ideas aren't working for you, and you just want to know the current best known strategies, you can rot13 the following spoiler:
