Drone (Swarm)

Debut wave 1, 1 hull points, speed 2.6, core damage 1. At wave 100: 8 hull points. Threat Director budget. Traits: Shielded, Insulated, Evasive, Ram.

1. Flies straight at the planet.
2. On spawn, 30% of standard hulls pick your nearest Tesla tower or the Orbital Station as their target instead of the core.
3. Motherships, warlords and Splitter wrecks release Drones that scatter for 0.55s, then turn in over 0.65s.

How to beat it: Flak or one missile; parry it back into the swarm.

Dart (Kamikaze)

Debut wave 2, 1 hull points, speed 4.6, core damage 1. At wave 100: 8 hull points. Threat Director budget. Traits: Insulated, Evasive, Ram.

1. Kamikaze run: it closes to a trigger range of 6–8.5 units, strafes sideways at 1.15× speed for 1.1–1.9s (that window shrinks every wave, toward ×0.35), then dives at 2.7× speed (a harder dive every wave, toward +30%). From wave 12 it dives at once when your laser overheats or your silos are reloading.
2. From wave 16, 30% fly in disguised: two flickering decoys split off beside it, and 1.2s later the real hull dashes in at 2.7× speed. Decoys pop in one hit.
3. Steers around Dilation Fog.

How to beat it: Flak it while it strafes, before the dive; keep heat and missiles in reserve from wave 12.

Debut wave 4, 4 hull points, speed 1.5, core damage 1. At wave 100: 22 hull points. Threat Director budget. Traits: Shielded, Insulated, Ram, Splitter.

1. Slow, armoured hull that flies straight in. Too heavy to parry.
2. Ploughs straight through Dilation Fog at full speed.
3. On spawn, 30% of standard hulls pick your nearest Tesla tower or the Orbital Station as their target instead of the core.

How to beat it: Missiles and Tesla; don't try to parry it.

Debut wave 5, 3 hull points, speed 1.9, core damage 1. At wave 100: 21 hull points. Threat Director budget. Traits: Shielded, Insulated, Jammer, Splitter.

1. Flies straight at the planet.
2. With the Jammer trait it jams missiles aimed at hulls within 3.5 units.
3. On spawn, 30% of standard hulls pick your nearest Tesla tower or the Orbital Station as their target instead of the core.

How to beat it: Missiles if it's Shielded; laser if it's a Jammer.

Carrier (Heavy)

Debut wave 9, 5 hull points, speed 1.2, core damage 2. At wave 100: 23 hull points. Threat Director budget. Traits: Shielded, Insulated, Jammer.

1. Big, slow hull that hits the core for 2. Too heavy to parry; shows as a large blip on the Threat Radar.
2. With the Jammer trait it jams missiles near it.

1. Kamikaze run: it closes to a trigger range of 6–8.5 units, strafes sideways at 1.15× speed for 1.1–1.9s (that window shrinks every wave, toward ×0.35), then dives at 2.7× speed (a harder dive every wave, toward +30%). From wave 12 it dives at once when your laser overheats or your silos are reloading.
2. Medium hull with 3 hull points: the toughest kamikaze.

How to beat it: Flak during its strafe; it takes three hits.

Shrike (Kamikaze)

Debut wave 6, 2 hull points, speed 3.8, core damage 1. At wave 100: 20 hull points. Threat Director budget. Traits: Insulated, Evasive, Ram.

1. Kamikaze run: it closes to a trigger range of 6–8.5 units, strafes sideways at 1.15× speed for 1.1–1.9s (that window shrinks every wave, toward ×0.35), then dives at 2.7× speed (a harder dive every wave, toward +30%).

1. Sector boss. Three phases, at full hull, two-thirds and one-third.
2. Each attack: a 1.5s warning (RAM IN), a 1s ram at 2.2× speed (+0.3× per phase), then its core is exposed for 2s at 0.45× speed and every hit deals +2.
3. Rams again every 10s, minus 2s per phase.
4. With Point Defense it shoots down missiles. Can't be parried or netted; resists Gravity Wells.

How to beat it: Prime a missile breach (3 laser hits), then focus fire while its core is exposed.

3. Three phases, at full hull, two-thirds and one-third. Can't be parried or netted; resists Gravity Wells.

How to beat it: Prime missile breaches; Pulse or flak the brood as it launches.

Lancer (Edge gunship)

Debut wave 14, 6 hull points, speed 2, core damage 2. At wave 100: 24 hull points. Every wave on top of the swarm. Traits: None.

1. Parks 78% of the way to a screen edge, in the middle of a side, swaying ±0.3 radians clear of the HUD.
2. A front deflector blocks laser and missiles within ±65° of its nose; hits from the side or rear deal ×3. A quarter of the missiles aimed at it swing wide to hit the flank.
3. Charges (0.9s, shortening toward 0.55s), then beams the shield every 3.8s (tightening toward 2.0s): 5 volleys, 4 from wave 30, then it dives at 2.4× speed.
4. Each beam burns 1 shield cell (2 from wave 34, 3 from wave 60, +1 every 30 waves after) and stops shield recharge for 2.5s. From wave 26 Lancers fire together.

How to beat it: Hit it from the side or rear; flanking missiles and the Deadstick get round the deflector.

Leech (Special)

Debut wave 10, 3 hull points, speed 3.4, core damage 1. At wave 100: 21 hull points. Threat Director budget. Traits: Insulated.

1. Latches onto the shield (6 at most; extras strike the shield instead) and crawls around it.
2. Drains one shield cell every 2.2s. Once the shield is down it bores into the core: 1 integrity every 4s.
3. Burn it off with the laser, the Orbital Station or a Pulse.

How to beat it: Laser, Orbital Station or Pulse burn it off the shield.

Herald (Command ship)

Debut wave 16, 10 hull points, speed 1.3, core damage 2. At wave 100: 28 hull points. Every wave on top of the swarm. Traits: None.

1. Command ship. Holds station 7.2 units out and circles.
2. Hulls inside its 4.5-unit aura fly 1.25× faster. Every 6s it signals the kamikazes and Reapers in its aura to dive together.
3. Commits to its own dive after 35s on station. Killing it freezes its escort for 1.2s. Too heavy to parry.

How to beat it: Kill it first: its escort freezes and the synchronized dives stop.

Reaper (Interceptor)

Debut wave 20, 5 hull points, speed 3, core damage 1. At wave 100: 23 hull points. Every wave on top of the swarm. Traits: Insulated.

1. Interceptor that hunts your Deadstick and Apex-9: it closes to 1.3 units and fires every 0.8s.
2. Each hit costs the Deadstick 3s of flight; 3 hits end a flight (and send the Apex-9 home).
3. With nothing to hunt it flies a kamikaze run like a Dart.

How to beat it: Shoot it before launching the Deadstick or Apex-9.

Scrambler (Special)

Debut wave 22, 8 hull points, speed 1.1, core damage 2. At wave 100: 26 hull points. Every wave on top of the swarm. Traits: None.

1. Heavy EMP hull that hits the core for 2. Too heavy to parry.
2. Reaching the shield, or dying within 3.8 units of the planet, fires an EMP: missiles in flight are destroyed, towers, station and silos go offline for 4s, laser heat jumps to at least 80%, and the Pulse recharge gains 2s.
3. Kill it far out.

How to beat it: Kill it far from the planet so its EMP misses your towers.

Sower (Minelayer)

Debut wave 28, 7 hull points, speed 1.6, core damage 1. At wave 100: 25 hull points. Every wave on top of the swarm. Traits: Insulated.

1. Minelayer: crosses the field at radius 5.6 dropping 6 mines, one every 1.4s (14 mines on the field at most).
2. Mines drift toward the shield at 0.22 units/s and hit it for 2. A missile passing within 0.55 sets one off (0.9 blast, 2 damage), so mines swat your salvos.
3. Laser the mines, or Pulse them. A mine burns out after 40s. Ploughs through Dilation Fog.

How to beat it: Laser the mines before your salvo flies through them.
