Base Defense in Steam Store
Release date: Q3 2017
What is Base Defense?
It is a co-op modification for Half-Life based on horde-style and RPG systems. You need to choose one of three classes, then join the fight against most dangerous monsters which are hunting you. Every class has it's own abilities and traits. You can be killing machine, strong support for your teammates or become the golden mean between those roles. In game you can get different items from the strongest enemies: helmets, armor and trinkets with magic powers. As you kill monsters you will get experience points and level ups.
Make your own epic character build and experience the most challenging battles!

New Features
The modification presents a lot of new features:
  • Improved AI
  • New weapons
  • Inventory
  • RPG system
  • New monsters
  • Player classes
  • Trading
  • New effects
  • Great soundtrack
  • Particle system
  • New maps
...and much more!

The war of good and evil was interrupted by alien invasion. Demons ran off, angels got back to heaven. Only humans left, surrounded by aliens. Here come 3 characters called defenders. They send all the humans to another realm, which is causing the merger of past and actual times. All events in the game are happening after the merger.

Some reviews from ModDB

3 of my friends got this mod without reading on what it was, just the title, then the download. We all played for like 3 hours, this is a really fun multiplayer mod. We kept making comparisons to the zombies gamemode in World at War, but this has a lot more stuff added to it, such as health kits, mana kits, Rick Astley, etc. Great mod, had a lot of fun.

Challenging, yet very fun! All the weapons feel extremely powerful, yet you can be overwhelmed in seconds if you don't know what you r doing! Amazing mod! :)

Base Defense brings really nice features to the traditional half-life, it shouldn't be ignored the fact that it was made by only one developer.
The horde system, plus the details that enhanced gameplay, weapons and enemies shows a nice quality, always trying to maintain the original half-life style on them, and the ost (which is Great) adds a nice feeling to the battle, for me, this deserves a 10/10.

The latest version of the modification you can get here:

It's easy. Just put the "bdef" folder to this path: "..\Steam\steamapps\common\Half-Life\"
After that restart Steam, Base Defense will appear in your Steam game library.
P.S. You need to have Half-Life in your Steam game library to be able to play the mod.

The game can be difficult for newcomers.
I suggest you to take a look at Base Defense Beginners Guide here:

It's free and awesome, give it a try! ;)

Smells something between TF2 and CS.

good mod, tons of weapons, fun with friends. But please make regular respawn like in DM or make rounds system like in CS

Glaster, thank you, but it doesn't have any problems like this if you play it in suggested OpenGL video mode. If it does anyway, then it's something wrong with your video adapter drivers.
