Firebase Gemini — Michael G. Thomas

It's 2436 A.D. and a violent uprising led by the Cult of Echidna is sweeping through the world of Kerberos. The Tigers, an elite special forces unit are securing a civilian outpost known as Gemini when the fighting starts. Little do they know that a great horde is coming for them and they'll have to transform the ruins into a defensible outpost if they're to have any hope of surviving the horror to come. Blood-crazed bands of religious Zealots murder loyalists wherever they are found, and rumours spread of untold horrors rising from the dark places, mindless beasts and creatures that will maim and kill without mercy. As darkness approaches, the Tigers at Firebase Gemini will have to face an enemy they could never have imagined, even in their worst nightmares.
