The first thing to know about Space Blaster is that your ship isn't cosmetic. There are five hulls, and four of them carry a signature ability that fires automatically during combat and quietly rewrites your survival plan. Under that sits a second layer — hangar upgrades, pilots, consumable boosters and cosmetics — all paid for with Nova Coins you earn by clearing missions. This guide walks through every ship, every mission, and where your coins actually go, using the real numbers from the game.
The five ships and their signature abilities
You start in the SR-7 Falcon and unlock the rest at the hangar with Nova Coins. Each hull has its own top speed, life count and fire-rate character, but the signature ability is what defines it. Here's the full roster:
| Ship | Cost | Signature ability | What it does |
|---|---|---|---|
| 🚀 SR-7 Falcon | Free (starter) | None | Balanced all-rounder: mid speed, three lives, standard fire rate. Your baseline. |
| 🚀 Vanguard Lance | 400 💎 | ⚡ Overdrive | Roughly every 16 seconds it triggers a ~3-second burst where your fire interval drops to about 45% — a big automatic damage window. |
| 🚀 Wraith Interceptor | 500 💎 | 💨 Phase Field | A flat 22% chance to completely dodge any incoming hit. The fastest hull in the game, but it trades away a little fire rate. |
| 🚀 Aegis Mk-II | 600 💎 | 🛡 Reactive Plating | Auto-blocks one hit that would have landed, then recharges over 10 seconds. Starts with four lives and the toughest hull. |
| 🚀 Tempest Striker | 800 💎 | 🔱 Storm Cannons | Fires a spread shot permanently — no pickup required. Wide coverage from the moment a mission starts. |
How to read the abilities
Overdrive is a rhythm. The Vanguard Lance ticks down a timer on the HUD, and when it hits zero you get a green "OVERDRIVE!" flash and a short spike of near-double fire rate. Because it's on a fixed cadence, the skill is positioning — line up a tough enemy or a boss window so the burst lands when it matters instead of into empty space.
Phase Field is pure variance. Roughly one in five hits simply doesn't connect on the Wraith Interceptor, which pairs beautifully with its top-tier speed — you're already the hardest ship to hit, and now a fifth of the shots that do reach you get shrugged off. The catch is the slightly slower cannons, so the Wraith wants you weaving through fire, not sitting still trading shots.
Reactive Plating is a safety net you can plan around. When it's charged, the Aegis Mk-II eats the next hit for free — you'll see a "REACTIVE PLATING!" flash and a burst of sparks — then it goes on a 10-second cooldown shown on the HUD. Combined with the ship's extra starting life, it's the forgiving pick for the harder missions where one mistake usually ends a run.
Storm Cannons changes the whole feel of the Tempest Striker. Spread fire is normally a temporary power-up; here it's always on. You give up a sliver of speed and fire rate, but you cover far more of the screen, which makes clearing dense waves and multi-target objectives dramatically easier.
The campaign: two arcs, ten missions
Space Blaster's campaign runs across ten missions in two connected arcs. Each mission has its own sector, story beat, objective and a named boss, and each one tracks a personal-best score you're pushing against a par target. The first arc is the core five; the second, the Crimson Frontier, ramps the intensity and the par scores hard.
| # | Mission | Objective / boss | Par score |
|---|---|---|---|
| 1 | Outer Orbit — Hold the Line | Defend the station · Gate Warden | 8,000 |
| 2 | Asteroid Belt — Clear the Way | Escort the freighter · Ore Crusher | 15,000 |
| 3 | Nebula Rift — Silence the Jammers | Destroy 3 jammers · Nebula Wraith | 25,000 |
| 4 | Machine Citadel — Breach the Core | Destroy 4 power nodes · Citadel Core | 40,000 |
| 5 | Void Gate — Close the Gate | Close the rift · Void Sovereign | 70,000 |
| 6 | Crimson Reaches — Blood and Fire | Hold position · Crimson Vanguard | 90,000 |
| 7 | Iron Wastes — Scrap the Fleet | Destroy 3 forges · Forge Master | 120,000 |
| 8 | Deep Crimson — No Quarter | Destroy 4 command towers · Tower Commander | 160,000 |
| 9 | The Gauntlet — Run the Gauntlet | Destroy the siege cannon · Gauntlet Warden | 200,000 |
| 10 | Blood Sanctum — The Red Sovereign | End the war · The Red Sovereign | 280,000 |
The objective variety is the point. "Hold the Line" is a straight defense; "Clear the Way" makes you babysit a freighter that can be lost; the jammer, node, forge and tower missions send you hunting specific targets while the rest of the fight tries to stop you. Storm Cannons shines on the multi-target objectives, while Reactive Plating and the Aegis's extra life earn their keep in the late Crimson Frontier, where par scores climb past a quarter-million.
The Nova Coin economy
Everything in the hangar runs on Nova Coins (💎). You earn them by playing — there's no requirement to spend real money — and a completed mission pays out from several stacked sources:
- Grade bonus based on how your score compares to par: S = 75, A = 50, B = 30, C = 20.
- First-ever clear of a mission: a one-time +100.
- New personal best on that mission: +25.
- No-death run (you finished without taking a life): +75.
- Daily login: +25 coins (plus battle-pass XP) the first time you play each day.
That structure rewards the same things good play already rewards — high scores and clean runs — so grinding coins and getting better at the game are the same activity. Wave milestones, achievements and battle-pass tiers drop additional coins on top.
Where the coins go: the hangar
Beyond unlocking the four paid ships, coins buy four other categories of power:
- Hangar upgrades — six permanent tracks, each with five levels: Hull Plating (block chance, +15% per level), Engine Tuning (+0.3 speed per level), Weapon Calibration (+8% fire rate per level), Reactor Boost (score multiplier), Pilot Reflexes (longer invincibility), and Targeting AI (longer homing). Early levels cost 150–250 coins; the top tiers of the pricier tracks reach 1,200–1,500.
- Consumable boosters — one-shot loadout items: Energy Drink (80, +20% speed for the mission), Warmed Cannons (80, start with rapid fire), Shield Generator (120, start shielded), Stardust Magnet (120, double coins this run), Continue Token (200, one free auto-revive) and Omega Strike (250, open with a bomb and spread fire).
- Pilots — a separate progression layer with passive per-mission bonuses. Vela "Nova" Kim is free and balanced; others trade stats (M. Steelhand is +10% damage / −5% speed for 600, Ada "Wraith" is +15% speed / −10% damage for 800), while The Archon at 3,000 stacks a bit of everything. Beating each of the first campaign's bosses also unlocks a co-pilot that stacks on top of your active pilot.
- Cosmetics — bullet skins, engine trails and explosion effects that are pure flair.
One more coin sink worth knowing: if you die mid-mission you can spend coins to continue on the spot, and the price escalates each time you use it in a run — 200, then 500, then 1,000, then 2,000. It's a genuine bail-out, but the rising cost is designed to make you think twice rather than lean on it every run.

Which ship should you buy first?
My honest recommendations, based on how each hull actually plays:
- Struggling to survive? Buy the Aegis Mk-II. The extra starting life plus Reactive Plating's free hit every 10 seconds is the biggest raw survivability jump in the game, and it's what gets most players through the Crimson Frontier.
- Want to clear waves faster? The Tempest Striker's permanent Storm Cannons trivializes the multi-target missions — jammers, nodes, forges and towers all go down quicker with spread fire always on.
- Confident dodger chasing high scores? The Wraith Interceptor is the skill pick: top speed plus a 22% dodge means an aggressive pilot can stay alive in fire that would end other ships, and speed makes farming par-beating scores easier.
- Boss-focused? The Vanguard Lance's Overdrive is a scheduled burst window — learn its cadence and you can dump a wave of extra damage right into a boss's vulnerable phase.
There's no single correct answer, and that was the goal. Every hull can finish both campaigns; they just ask you to fight differently. Pick the signature ability that patches whatever keeps ending your runs, fund it with clean high-scoring clears, and let the hangar upgrades and pilots carry you the rest of the way to the Red Sovereign.
