Age of Origins Infinite Zombies Guide: Layout, Boosts & the Friday Routine

Part of the Tower Defense series:

• Tower Defense Guide: Tower roles, scaling, and the Classic campaign.
• Beginner's Guide Hub: The full new-commander picture.

Quick Answer

• Infinite Zombies unlocks at Main Hall 10: endless escalating waves, one challenge per day, and you're scored on survival — kills become Points, Points become TD Coins.
• The routine that matters: play one real, fully-boosted run on Friday right after the weekly reset, then hit Auto the other six days to re-collect your best score's coins without playing.
• You can restart free within the first three waves (boosts aren't consumed), and you can leave mid-run and resume.
• Core layout: slow towers on the middle tiles of each side, Lasers everywhere else; boost the middle Lasers first.
• Spend TD Coins on Blueprint Chest S and Officer XP in the Exchange Store. That's the whole reason this mode exists.

What Infinite Zombies Actually Is

Where the Classic campaign is a puzzle you solve once, Infinite Zombies is a paycheck you optimize forever. Waves escalate endlessly — nobody "wins" — and when your base finally falls, your kill Points convert into TD Coins. One challenge per day, unlocked at Main Hall level 10.

Two mechanics turn it from a daily chore into a weekly one:

1. Auto. Once you've set a score, the Auto function re-collects TD Coins equal to your best run, daily, without you playing a single wave.
2. The weekly reset lands Friday, after server reset.

Put those together and the optimal loop is obvious: one serious, boosted run every Friday to set the bar as high as possible, then six days of Auto collection off that score. Veterans treat the Friday run like a raid night; everything else is passive income.

One more forgiveness mechanic worth knowing: restarts within the first three waves are free — your consumables and boosts aren't spent. If your upgrade offers open badly (more on RNG below), reset without guilt.

The Layout That Works

The map funnels zombies from multiple directions toward your central base, with tower slots grouped in tile clusters along the lanes. The community-settled layout, refined over years of score-chasing:

• Slow (EMP) towers on each middle tile, left and right — top-left middle, top-right middle, bottom-left middle, bottom-right middle. Slows in the middle of each lane stretch every zombie's exposure to your damage.
• One extra slow on the bottom tile of the bottom-middle cluster — the last net before zombies walk into your base.
• Lasers in every other slot. Laser damage ramps the longer it holds a target, and slowed targets are held targets. Lasers plus stacked slows is the entire engine of a big score.
• Lower-level cities (around C22 and below): your Equipment power probably isn't carrying Lasers yet — run paired Rocket turrets facing each other across the bottom instead, and migrate to the Laser build as your account matures. (Why Equipment power matters for Lasers is covered in the tower scaling section of the main guide.)

Upgrade discipline within the run:

• Boost the middle Lasers before the edge Lasers. Middle positions keep targets in range longest, so ramping damage lives there.
• Boost the top side before the bottom. Kills up top thin the pressure that reaches the bottom — the top lane is load-bearing.
• Fill empty edge squares with cheap towers rather than leaving them bare — they contribute chip damage and soak targeting — but don't sink real upgrades into them.
• If the upgrade RNG keeps offering Rocket damage you can't use, place a Rocket somewhere useful and stop wasting offers.

Boost Picks: The Priority Order

Between waves, the game offers you picks — weapons, upgrades, and reward modifiers. The community priority order:

A-Bomb → Climate Controller → Lasers → Rockets → Slow Tower → Area Freeze → Energize → Area Bomb.

A-Bombs top the list because in a score economy, a screen-clear at the right moment is worth more waves of survival than any incremental tower buff — using consumables isn't cheating here, it's the strategy. Two subtler rules from the same players:

• Take flat resource rewards over percentage-based ones. The flat amounts are simply better in this mode's math.
• Take reward quality upgrades before "reward amount +1." A better chest beats one more mediocre chest.

The TD Coin Economy

TD Coins spend in the Exchange Store, and the pecking order is settled:

Buy	Approx. cost	Why
Blueprint Chest S (Superior)	~200 coins	Blueprint S fragments — the route to the yellow comprehensive extension on Elite Equipment
Officer XP	~200 coins	Always-useful officer fuel — see officer types
Blueprint Chest A (Superior)	~120 coins	Fills the standard extension slots
Power Ore	—	Steady equipment progression

(Prices drift with updates — sanity-check in your store.) The long game is Blueprint S for your gear extensions — which loops back into tower defense itself, since Equipment power scales your Lasers. Infinite Zombies quite literally funds its own high scores. The equipment systems these blueprints feed are broken down in the officer & elite equipment guide.

What Counts as a Good Score?

Benchmarks float around the community: 30,000+ Points is bragging-rights territory for developed accounts, and scores in the 40k+ range have been posted even without spending A-Bombs. Don't measure yourself against those in your first months — your score tracks your account's four power categories more than your APM. Set the best bar you can each Friday, Auto the rest of the week, and the number climbs on its own as your account grows.

The Routine, Compressed

1. Friday after reset: full run. Boosts on, A-Bombs ready, layout above, restart if the first waves' offers are garbage.
2. Saturday–Thursday: open, tap Auto, collect, leave.
3. Spend coins on Blueprint S + Officer XP.
4. Watch the score creep up weekly as your research, gear, and officers grow.

Ten minutes a week for one of the most reliable income streams in the game. There is no excuse to skip it.
