Introducing Frontlines, a small mod with a big ambition. Frontlines plans to bring new exciting content, revitalize the stale game-play mechanics of Zero Hour, and to provide both an interesting single player and multiplayer experience. Frontlines is an open-source mod, our assets are free to use, as long as we are credited.
So my original plan was to revive this thing: Moddb.com unfortunately the model has been lost. So instead, I reworked another unreleased thing instead.
The Slammer Cannon was originally an upgrade for Tao's Inferno that gave it magnetic homing AT shells, but it didn't really feel right to me, so I reworked the addon into a heavy AA railgun instead: Youtu.be
its a great addon as it can allow you to finally defend your artillery from aircrafts by upgrading a few with Anti-Air Cannons.
