Zindex
About Zindex
Zindex is a free online 3D survival game from Mirra Games that drops you into the middle of a zombie apocalypse with no one around but hungry, hostile zombies. Your goal is to find a way out of the epidemic-stricken zone, and the key to escape is repairing an abandoned radio tower to call for help. Along the way you'll need to explore houses, scavenge for useful items, and fight off hordes of zombies without running out of stamina or health.
Playable free in the browser with full support for mobile devices through on-screen touch controls, Zindex mixes exploration and resource management with tense, close-quarters combat. Every house you enter is a gamble between useful loot and a zombie ambush, which keeps the tension high from the moment you start scavenging to the moment the radio tower finally comes back online.

Repairing the Radio Tower
Your ultimate goal in Zindex is contacting survivors through the broken radio tower, but getting it working requires completing a series of tasks first. Start by exploring the surrounding area and searching nearby houses for useful items, using the map (M) to keep track of good scavenging spots. Along the way, keep a close watch on your stamina and health bar so you don't get caught out in the open when zombies show up.
Surviving Zombie Attacks
Zombies in Zindex don't hold back, and they'll often outnumber you if you let them group up. Fight them one at a time whenever possible, retreating to a chokepoint rather than getting surrounded in the open. Stamina management matters just as much as combat skill — running out mid-fight leaves you unable to attack or dodge effectively, so pace your engagements and avoid taking unnecessary hits to prevent infection.
Scavenging Useful Items
Exploring houses for drawers and refrigerators full of resources is central to surviving in Zindex. Coffee temporarily halts stamina consumption, letting you push through a tough fight or a long sprint. Bandages and first aid kits restore lost health, and a defibrillator can revive your character if you go down, making it one of the most valuable items to keep in reserve.
Tips for Winning at Zindex
Always check your stamina bar before engaging multiple zombies, and back off to recover if it's running low rather than fighting through an empty tank. Stockpile bandages and first aid kits before pushing into unexplored, zombie-heavy areas, and keep a defibrillator on hand as an emergency backup. Use the map (M) to plan efficient scavenging routes instead of wandering aimlessly and risking unnecessary zombie encounters.
