Patch NotesOfficial
v0.8.5 Full Game Rework
Preliminary update to bring Invasion: Phoenix up to modern standards while I finish off the Earthen Union campaign. It's taking longer than expected to get the campaign finished/balanced so I figured I'd release an update so the game has all its new bells and whistles before campaign officially drops. New things: - Virtually everything has been re-written from the ground up, from AI to unit functionality - Fog of war now fills in - New 'detected' feature so units actually have line of sight and must scout enemies - Completely revamped Combat Powers - Updated UI: Game Setup, in-game Combat Powers panel and Reinforcement panel - Massive performance gains - Added wildlife - Modding now exists. Users can now modify units/combat powers/defensive structures through the included .csv files. This is still limited at the moment, and changing certain things to crazy numbers may cause the game to crash, but the bulk of it works, and it will improve over time. - Too many things to list. As I said, virtually the entire game has been rewritten from the ground up. Everything just... works better than it used to. - In the backend, the majority of the Earthen Union campaign is created and done, I am just focused on balancing/getting it functional. Massive thanks to everyone who has purchased the game and given me their support! You are noticed and appreciated :) Let's bring back gaming!Read full article on Community Announcements (Sursion)Patch NotesOfficial
