Patch Notes
(Click Show details for a full breakdown of the changes)
[expand type=details]
- Added an L-shaped prefab to the list of dynamic prefabs for civvies to use
- Fixed civilian walls not running some BeginPlay logic they needed
- Civvie walls now properly landscape-away trees/etc. when their base spawns
- Added basic nav check, other structure check, and 'corner traces' to civ prefab placement to improve placement
- And added a 'Tiny' prefab, so some zones that other prefabs won't fit in can still hopefully get them, but didn't hook it in (seemed too comical for the time being)
- Lowered devirtualization range by 2000uu (from 20K to 18K). Not seeing many folks complain about units 'popping out of nowhere', so wanted to drop the range a bit to boost performance
- increased the rate of 'distance checks' that the UnitMovers do to determine if they should virtualize or devirtualize (since this check seems very cheap). Performance tweaks
- Added an early 'bounding box' check when spawning civvie prefabs, to reduce the number of situations where a civvie camp spawns too close to another
- Implemented logic so civvies will use their resources (currently, 350 supplies) to purchase a stronghold position in their zone, if there is one and if they already have three regular bases claimed
- Civilian groups will now roll aggression at their creation and have wars/infighting across groups. Some groups will naturally be more aggressive now
- Civilian groups can assimilate other groups into theirs and expand their influence across zones
- Adjusted Civvies to utilize their Aggression stat (range 0.0-1.0) when calculating whether or not they should fight the player (when rep's low, it acts as a 'multiplier' to the 'attack player' roll: i.e. (1.0 + Aggression) * Roll == ModifiedRoll)
- resolved a save/load issue so that, when a dynamic civvie faction loads warfare against another dynamic civvie faction, if the other faction doesn't have their central spawner loaded yet, it can hook into a delegate for when that CentralSpawner gets set
- Quick update to some of the prefabs in Treasure Island to resolve some small discrepancies with the pre-calculated bounding boxes (likely wasn't needed, difference was past the decimal)
- Quick bounds fixes to the Presidio strongholds 5-8 in line with the new things I added from my previous commit (Efrain if you see this, don't worry, I added new stuff so I had to re-do the calculations. You're fine. :P )
- Updated the 'Offset Non-Spline Transforms' functionality for setting up Civilian prefabs to also adjust the actor's world location in the opposite direction, so you don't have to worry about 're-scooting' the actor back into position when setting up pre-placed prefabs (such as strongholds)
- Added sfx for avenger and hooked it in avenger bp
Please note the following going forward (Restart your game/steam to get the update if needed

[ 2023-04-27 05:10:56 CET ] [ Original post ] 
The Pangu Virus has been unleashed in San Francisco, turning thousands of innocent lives into mindless beasts that feel no pain and have no fear of death. With each passing hour, the Pangu Virus evolves, creating new and ever more horrific mutations with one goal in mind… Spread.

You are Captain Winter, a military officer fighting alongside the Center for Epidemic Research and Control(CERC). With a massive arsenal and the resources of the US Government behind it, you and CERC will stop at nothing to ensure the terror of the Pangu Virus does not escalate beyond containment, even if a whole city and millions of lives must be sacrificed.
- Cepheus Protocol is inspired by classic RTS games such as Company of Heroes and World in Conflict, alongside the book World War Z.
- Survive if you can against a relentless enemy that evolves and grows more powerful with each day.
- Build specialized units from a variety of bases that can be placed anywhere in the open-world map.
- Battle those infected by the Pangu Virus across four open-world islands, featuring unique and challenging environments.
- Choose from three combat tiers that play to your style. Each tier has specialized units, equipment, and weaponry.
- Engage a relentless horde of infected which numbers grow larger and stronger with each territory captured as you battle for control of San Francisco.
- Hunt Patient Zero, who races across the city seizing territory. Each capture zone increases her population as the virus spreads and possesses all organic matter.
- Form an alliance or side against the Anarchist and Police factions, which struggle to survive among the madness that has enveloped San Francisco.
Note: Steam Remote Play is for allowing your friends to try out the game if you already have purchased it. It's not for online co-op: that is is planned in the current roadmap, but is not complete yet
