TEGRA: Zombie survival island

The endgame here is not a helicopter rescue or a cure. It is a portal. You gather scrap and lumber like any survivor, but the goal TEGRA sets is building a gateway between worlds, and some of the things trying to kill you have already come through it, venomous spiders, magical creatures, mutant bosses that do not belong in a normal zombie game. Combat is first-person, and your arsenal grows from an axe and a bow to shotguns and a flamethrower as your crafting deepens. Between raids you reinforce walls, set traps and hold the perimeter against undead waves and human marauders both. Skills level up, so a heavy-armor bruiser and a fast scavenger play differently. It runs offline, which matters for a game this large. Forests, dead cities, forgotten bunkers, and something stranger waiting past the gate.
