Nova Defence
A one-finger defence game for iPhone. Tap to fire a pulse, stop the attack on your data core, and never hit the blue allowed traffic. One leak and the kernel is gone.
iPhone first. Android later.
Inside the game
Wave 17 in Endless. Each pulse leaves a purge ring, and every extra threat caught in one blast multiplies the score.
Five ways to hold the line
-
Tap anywhere to fire a pulse.
3 charges to start, one more every 7 waves, up to 5. A charge returns every 0.62 s. Aim where the threat will be.
-
Laser sweeps a whole lane.
22 energy to arm, then 25 a second for up to 4.5 s. Drag to turn the beam.
-
Shock clears the ring around the core.
55 energy. Wipes every threat within reach and throws the rest back. It pulses when you need it.
-
A turret takes aim on its own.
80 energy for 3.5 s of automatic fire. Precise hits fill your energy; misses don't.
-
Never shoot the blue traffic.
Allowed packets are harmless. Hit one in the campaign and you lose a star and the alarm climbs a level, up to three.
Five modes, opened by level
-
Network
Take over the campus: five nodes, fixed waves, a boss at the end of each and three stars to earn.
From the start
-
Endless
Wave after wave from wave 1, with no end. Your best score and wave go to Game Center.
Level 3
-
Blitz
Two minutes against the clock, threats arriving faster. The clock stops between waves; survive it for TIME UP.
Level 6
-
Daily
Today’s seed: the same waves for everyone, shop upgrades switched off, one try a day.
Level 10
-
Root
One life. Armour does not count, the first leak ends the run, and every credit counts double.
Level 15
Every mode raises your level, about one every six minutes of play. A mode you have not played yet says NEW in the menu.
The campus network
| Node | Waves | New threat | Rule |
|---|---|---|---|
| dorm-wifi | waves 1–5 | — | boss at the end |
| library-proxy | waves 2–6 | Spiral | allowed traffic ×2 |
| lab-node-01 | waves 4–8 | Ghost | worms ×2, early |
| registrar-db | waves 5–10 | Trojan | probes ×2, early |
| campus-dc | waves 7–12 | Orbiter | DDoS at wave 3 |
Nodes open one by one. The boss has two phases on the first three nodes and three on the last two. A captured node can be replayed any time for its stars; upgrades from the shop make the last two fair game.
Questions
PrivacyDoes it track me?
Not without your yes. There is no account, no analytics and no server of ours. Players under 16 never see personalised ads. From 16, ads are personalised only if you agree in the consent dialog (and on iPhone, Apple’s tracking prompt). Privacy policy
No AdsHow do I restore “No Ads” on a new phone?
Sign in with the same Apple ID, then open Shop → Restore purchases. Rewarded ads stay optional either way: you only see one when you ask for a second chance or double credits.
ConsentHow do I change my ad consent?
Open Settings → Privacy options. The button appears where consent applies, and the game keeps working whatever you choose.
ProgressWhere is my progress stored?
Only on your phone, and in your own phone backup if you use one. Settings → Reset progress (tap twice) clears it; deleting the app removes everything.
DifficultyThe last nodes are too hard.
They are meant to need the shop: replay captured nodes for credits, upgrade blast, charge and recharge, then come back. Tell us how it feels at support@berkeyildirim.net. The game is tuned from player feedback.
ModesWhy are some modes locked?
They open with your level, and every mode raises it: Endless at level 3, Blitz at 6, Daily at 10 and Root at 15. Scores in Blitz, Daily and Root are kept per mode; Network and Endless feed the Game Center leaderboards.
