Local Addons (10)
This update includes a new local addons system. Local addons allow us to implement small, toggleable adjustments to various aspects of the game, without directly editing the engine's code. If you have made an addon in the past or are interested in producing local addons for P2:CE, see here for submission guidelines / info: https://github.com/StrataSource/p2ce-addons
A list of local addons which have already been added can be found below:
- Added "Portal 1 Portal Gun" local addon.
- This replaces the portal gun's viewmodel, particles and SFX with Portal 1's, and changes the particles and sfx for portals. (Special thanks to Electrodynamite12 for providing updated particles!)
