Radius Raid Unblocked

Radius Raid splits your hands between two jobs. Your left hand steers a little ship around a starry arena, while your right hand swings the mouse to aim, so you can flee one way and fire the other. The arena stretches well past the edges of your monitor, and enemies keep sliding in from beyond the edges. Jack Rugile wrote it for the js13kGames contest in 2013, and every ship, spark and sound effect is generated by code. On FreezeNova it plays unblocked in any desktop browser.

What Happens in a Round

Click PLAY and you are dropped into the middle of the arena. The nose of your ship tracks the cursor, and a held left click sends out a steady line of shots.

You have a green Health bar instead of lives. Nothing fires back at you. Damage comes purely from collisions: an enemy pressed against your hull eats into the bar, and the longer it stays in contact, the more you lose. Once it hits zero, you get a results screen listing your score, level, kills, shots, power-ups collected and time survived.

Every kill nudges the Progress meter along the top edge. The first level asks for 17 kills, and each later one asks for seven more than the last. Fill the bar and a new enemy type appears. Basic foes give 5 points while the toughest pay 65.

Some arrivals change how you play. Splitters burst into four smaller enemies. Stealth ships are almost invisible against the stars. Spawners keep releasing quick little chasers until you destroy them.

Fallen enemies sometimes leave power-ups that run on a timer, with their countdowns shown at the lower edge. There are five: a health refill, an enemy slowdown, faster firing, a three-way spread and shots that pierce through targets.

Survival Habits

Early on, the arena feels roomy. By level six or seven it does not. These habits help:

1. Drift rather than stop. The ship keeps its momentum and glides to a halt, so a quick tap is enough to slip around a chaser. Holding still is how health disappears.
2. Use the mini-map. Anything beyond the visible area appears there as a dot, which gives you time to swing your aim at a pack before it arrives.
3. Kill splitters at long range. Popping one at close quarters surrounds you with four new threats.
4. Make spawners your first target. Every second one lives adds more chasers to the field.
5. Turn on autofire for marathon runs. Press F and the ship shoots on its own, leaving you to steer and aim. The setting is remembered next time.

One more detail worth knowing: the healing pickup appears only once you have lost more than about a tenth of your health, so you will see more of the attack power-ups when you are healthy.

Who Will Enjoy It

Radius Raid suits anyone who likes twin-stick style shooters but only has a keyboard and mouse. A round can last two minutes or twenty, and the saved stats give you a reason to come back. If you prefer bouncing shots off walls, try Tank Ricochet. The whole arcade games list has more score chasers in the same spirit.
