[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 not a game, Synergy is a mod for a couple of games that allows you to play Online.
I played Synergy with my best friend, Origibro, here on steam.
I enjoyed it very much, we played Half Life 2, we started from the beggining of the game.
Everything is same as playing in Single Player, only is that it's alot better playing with a friend or two.
I hope I continue playing this awesome mod, and I hope my friends want to play it with me as well!

My Rate: 11/10 Awesome.

This is a must have for fans of Half-Life 2!

To put it short, this is a mod that let's you play Half-Life 2, Half-Life 2: Episode 1, and Half-Life 2: Episode 2 and let's you play it co-op!

How is that not awesome?!

If you have Half-Life 2 GET THIS NOW!
