About SIPHON: the 2D platformer where you steal every hero's power

The premise

The city is guarded by a league of nine heroes. Doctor Siphon has a different plan for them. Pick a hero, beat them in a one-on-one fight across rooftops and ledges, and drain their power for yourself. The order is yours to choose. Once eight have fallen, the league's leader, Paragon, steps forward for the final fight.

How stealing powers works

• Every hero you defeat gives you their power for the rest of the game.
• Each power you absorb also gives you more health and harder punches.
• The heroes fight back harder too. Every hero you've absorbed makes the rest tougher, and high-threat heroes are far stronger from the start.
• Your progress saves in your browser, so you can come back and keep conquering.

The nine heroes

Captain Bolt

The Fastest Man Alive

Kick off the air itself. Jump again while airborne.

Frostbyte

The Cold Front

Power you steal: Frost Lance

Fire a shard of ice that freezes a hero solid for a moment. Costs energy.

Threat ▮▮▯▯▯

Blaze

Living Inferno

Power you steal: Hellfire Bolt

Hurl fireballs. Costs energy, which refills over time.

Threat ▮▮▮▯▯

Wraith

The Unseen Blade

Power you steal: Shadow Step

Vanish and reappear behind your enemy — even behind a shield.

Vitalis

The Undying Light

The final boss

Paragon

Leader of the League

Power you steal: Paragon's Might

Your punches hit 50% harder. The strongest hero's strength is yours.

Threat ▮▮▮▮▮

Paragon unlocks only after the other eight heroes are absorbed. He has by far the biggest health bar, uses every other hero's power against you, and gets deadlier at two-thirds and one-third health.

Controls

SIPHON is played with a keyboard. You start with the basics and unlock more moves as you absorb heroes.
