Buy Synergy

Imagine being able to play Half-Life 2 and other Half-Life mods cooperatively with your friends? That’s the experience this new mod, Synergy, gives you. It’s as if there’s no Gordon Freeman—just a chaotic bunch of no-name adventurers fighting against the worst the Combine has to offer. If you’re done with Half-Life 2, you can also install and play other Half-life mods to continue your journey. Syngery contains fan-made maps, as well as support for mods MINERVA, Half-Life 2: Riot Act, and City 7: Toronto Conflict.

Play with up to 10 members of the resistance force of City 17. Take up the Half-Life arsenal, including rifles, gunboats, and bug bait, and drive the Combine forces from Earth. Fight beside your friends and win through the worst odds. With the Synergy mod, you’ve got an army at your back to help take back the planet!
