The Workshop for Serious Sam HD: The Second Encounter (I'm going to call it SSHD:TSE for short. Catchy, right?) has been operational for a while now with fans creating content ranging from new maps to player models, weapons, and new enemies. As of today, the SSHD:TSE Workshop
is fully visible to all and waiting to make your game even more awesome.
There are over 45 Workshop items available with more to come. Plus, the game is a whopping 75%
off today, so there really is little reason to not get the game and join the HD chaos right now.
Interested in modding the game yourself? Croteam has put together a handy wiki[serioussam.com]
with information on modding and uploading to the Steam Workshop.
