THERMAL RUNAWAY

One room. One hundred waves.

• 100 waves across 10 levels — a full run is 35 to 50 minutes
  
• Waves are generated rather than scripted: the same rules, a different fight
  
• A run can be suspended and resumed, but never checkpointed. Death ends it

The build is the game.

• 62 upgrades and 13 Protocols that combine rather than add
  
• Ricochets that split on every bounce. Lightning that conducts through frozen targets
  
• Echoes of yourself that keep firing your weapon after you have moved on

It escalates on eleven axes, and health is the smallest of them.

• 4 enemy archetypes, promoted to Elite and Prime ranks as the run goes on
  
• The chamber itself turns against you: the floor is not neutral by level 9
  
• Difficulty you can out-build is difficulty worth having

THE OVERSEER is at wave 100.

• A multi-phase fight against everything the facility learned about you
  
• Endless Overload cycles after it falls, for anyone who wants the number to keep going
  
• 32 achievements, most of them for the things you did not have to do

Everything you see is generated.

• Keyboard, mouse and gamepad, fully remappable, with on-screen prompts that follow the device in your hands
  
• Auto aim, adjustable screen shake and flashes, high-contrast mode — playable on a keyboard alone
  
• 20 languages
