The Crystal Mission a Sven Co-op campaign addon

Hi everybody !

I'm neophus a fan since the beginning of Half-life and I created a new campaign to play and enjoy with friends for the most famous coop MOD on goldsrc which is Sven Co-op.

It includes 4 maps with custom textures and models. It includes secret areas and easter eggs too so look closely ! I recommend to play with campaign with 3/5 players to enjoy better the experience.

This campaign is the first version because I'm going to create 2 new maps in a second version.

I hope you will enjoy this campaign as I enjoyed to created it !

Special thanks to many members from the Sven Co-op discord : Pyroxyde, Loulimi, Joce, Trempler, I_ka, Hezus, Outerbeast, H² and especially Sparks who helped me a lot !

IMPORTANT :
For whose who downloaded an old version (1.11 or older) please delete crystal_mission_1.bsp, crystal_mission_2.bsp, crystal_mission_3.bsp and crystal_mission_4.bsp
Delete cross_paths.wad, halflife_hd.wad and jpsecurity.wad too. Then download the new zip file and replace all the files with the new version
