How the run actually behaves
Space Survivor by Inlogic Software adapts the bullet-heaven formula for 800×600 portrait play, making it effortless to play one-handed on mobile or with a simple mouse drag on desktop. You pilot a lone space marine surrounded by alien swarms; your equipped weapons fire automatically at the nearest targets while you weave through enemy rings to scoop up XP gems.
Because the portrait viewport is narrower horizontally than landscape games, vertical lane control and timing your field power-ups (bombs, magnets, and shields) determine whether you survive late-wave alien encirclements.
Controls that change the run
| Action | Input | Why it matters |
|---|---|---|
| Steer Space Marine | Mouse Hold & Drag / Touch Thumb Drag | Use figure-eight vertical loops rather than hugging the left or right screen edges. |
| Pick Weapon / Ability Upgrade | Click / Tap Upgrade Card | Always pair a single-target high-fire-rate gun with a radial drone or orbital shield. |
| Trigger Field Power-Ups | Walk Over Arena Drops / Tap Active Item | Leave screen-clear bombs and magnets on the floor until a dense wave closes in. |
Space Survivor — {game} systems, roles, and pick order
| Name | Category | Role | What to do with it |
|---|---|---|---|
| Plasma Rifle (Auto-Target) | Primary Weapon | Closest-Threat Lock | Fires rapid bolts at the nearest alien, carving an escape path in whichever direction you kite. |
| Orbital Drones & Forcefield | Defensive Tech | 360° Contact Buffer | Essential in portrait mode where horizontal dodging room is tight. |
| XP Gem Magnet & Rate | Passive Upgrade | Safe Leveling | Lets you pull dropped gems without stepping back into alien spawn clusters. |
| Emergency Field Items | Tactical Pickup | Wave Reset | Instant heal, magnet sweep, or blast wave to survive elite alien rushes. |
Three-phase route
Early Waves · Vertical Figure-Eight Kiting
In a portrait arena, enemies spawn closer to the left and right edges. Move vertically down the center, then loop around the outside to vacuum gems.
Mid-Game Upgrades · Combine Piercing Fire with Orbitals
Single-target shots get overwhelmed when alien bugs stack 5 deep. Add piercing lasers or orbital drones by level 5.
Late Waves · Save Arena Power-Ups for Pinch Moments
Memorize where health and bomb pickups drop on the floor and kite near them until an elite wave traps you.
Questions players actually hit
Can I play Space Survivor directly in my browser?
Yes. Click 'Play Now' at the top of this page to launch the HTML5 game in your desktop or mobile browser.
Why is Space Survivor in a vertical/portrait aspect ratio?
It is designed at 800×600 portrait resolution so mobile players can control movement with one thumb while desktop players can drag with the mouse.
How do I avoid taking damage when picking up XP gems?
Clear a forward lane first, loop around the pack in a wide arc so enemies trail behind you, and upgrade pickup magnet range early.
