[Weekly] Time to say hello again. 56.13

Not many updates this week. There isn't a current
changelog for the new 56.13 of synergy.

There have been some new added features which are still a Work in progress.

For instance the shell casings update not many have noticed yet but if you shoot the smg1 or shotgun you will see that actual physics shell casings come out and hit the floor just as a normal shell casing should. They can be stepped on and moved around (client side)


Also donators have a new addition to their playermodel selection



Come back next week for the next news post

Keeping it simple and updated

As posted on www.synergymod.net

Just a heads up. We'll try our best to keep you guys updated as much as possible.
Our coder has thrown a few updates in the past week that fixes a few issues (no changelog for that),
As you know we barely post news and updates on what's going on. We'll try to keep our changes in order.


Rebel rush event is not yet scheduled. I will keep you posted.

Every week I or another team member will be posting some updates/changelogs.
Just to keep you guys in the "know".

Thank you so much for being a part of Synergy till this very day.
We hope to release some crazy new things very soon.

Synergy is probbably one of my favorite multiplayer sourcemods. It updates still to this day and you can screw around with your friends in half life 2 and the episodes and other mods maps. This mod is probbably one of the best multiplayer source mods out there!!
