I just uploaded GH2 v0.628 to SourceForge. I haven't started on the major rebalancing things yet, but wanted to release one more time first. This version fixes some minor bugs, adds shadows to the 2D display, and features the first special ending: Peace and Love. So far, this ending is only accessible if your core story enemy is one of the pirate factions and you personally belong to one of the Spinner military, political, or police factions.
Try it out, let me know what you think. Next update should be in about a month.
