Blue Light

Blue Light is a modification for Garry's mod that combines Half-Life 2 and Left 4 Dead 2.
There are:

• Exciting battles with zombies and antlions
  
• Caves like in Half-life 2: Episode Two
  
• Deadly traps and interesting puzzles
  
• Well designed and optimized locations
  
• Updated interface and 30-minute level

Explore the world on your own or with friends!

Your working day was ending and you were about to go home when you suddenly heard gunshots.
Combines. They forced you to go deeper into the complex. It didn't get any easier, because the place quickly filled up with zombies and antlions. Perhaps... you'll find other survivors...

• I recommend to disable all mods and restart the game!
  
• All the content you need is already included
  
• Map name: bl_blue_light_c1m1
  
• Gamemode: Blue Light
  
• Next level status: Coming in April 2025
  
• The mod replaces some sounds and models. After completing the level, disable this mod

If you want to make the game more difficult - hard mode is what you need:

• There will be more enemies
  
• Most of the interface will be disabled
  
• Supplies will be harder to find

By downloading this mod, you agree to the collection and processing of data such as: Steam username, Steam ID, and all achievements earned inside this mod.

Yes, the mod collects information from all playing players:
1) Positions on the map
2) Camera angles
3) Health
4) Armor
5) Current weapon in hands
6) The number of rounds in the clip
7) Number of additional ammo
8) Player FPS
9) SteamID
10) Steam nickname

The mod collects user settings too:
1) Degree of smoothing MSAA
2) HDR degree
3) V-sync
4) Is the "heavy" shader used for the flashlight
5) Screen resolution

Mod also collects data about all the killed NPCs and about all the drops that spawned for the player

The data will help me understand where the problem areas are on the map. Players do not have enough first-aid kits? Too many enemies? Low ammo? Do players often die in a certain place?

I need the data to make more awesome levels in the future!
