## What is Kessler Orbit?

Defend Earth from everything the sky throws at it. Eight weapons, three orbital tracks, a planet that keeps growing between missions - and waves that keep coming back harder.

A tower defense you build once and keep improving: every upgrade tells you what it does, every enemy tells you what beats it.

EIGHT WEAPONS, YOUR WAY
- Missiles always hit. Railguns punch through rock and armour. Flak shreds light hulls and shoots down salvoes. Tesla coils jump from target to target, gravitons slow whole clusters, drone swarms hunt on their own.
- Four abilities per weapon, on or off: twin launch, burn-through, shrapnel, twin rails, static field, thermal shock, singularity, kamikaze drones and more.
- Enemy intel in battle: hull, speed, armour and the best counter for every attacker.

OWN THE ORBIT
- Three tracks, eight slots each. Platforms come as module cards from supply crates.
- Four identical cards merge into the next grade: standard, reinforced, epic, legendary.
- Reactors, fire control and point defence upgrade every track.

A PLANET THAT KEEPS WORKING
- Habitat domes, industry, bunkers, hangars for fighters and bombers.
- Production continues while you are away. Nothing between missions is ever lost.
- Watch the Earth turn, from the day side to the city lights of the night.

SOMETHING EVERY DAY
- Daily supply drop just for opening the app.
- A 30-day reward calendar with a milestone every fifth day.
- Three daily missions, a season pass with thirty levels, ten ranks from Recruit to Guardian of Earth.

WHEN YOU HIT THE WALL
Colonise a new world: colony cores stay forever and lift everything that follows.

FAIR BY DESIGN
Free to play. Purchases speed things up but are required for nothing. Crates cost in-game gold or gems only, and their odds are shown before you open them. Sound and music are optional.

SUPPLY LINE SUBSCRIPTION
Supply Line - EUR 4.99 per month (price varies by region). Delivers gems and gold every month and speeds up building. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours before the period ends. You can manage or cancel it in your Apple Account settings after purchase.
