Apex I Engine in SimpleRockets 2

Our newest engine, the Apex I is an absolute beast. It's heavy, expensive, and drinks RP-1 like there's no tomorrow, but it will have the power to get even your most poorly engineered contraptions into space.

It dwarfs the Mage I engine in size, power, and visuals.

Here are the details:

• Thrust: 3,200 kN

• Mass: 3,500 kg

• Price: $8,500,000

• Height: 4.2 m

• Diameter: 3.0 m

• Max Gimbal Angle: 2.5 degrees

• Fuel Consumption: 1,350 L/s

• Specific Impulse: 298 s

Here's a bonus shot of it in a highly ill-advised use case.

Can anyone guess the inspiration behind this engine? I'll give you a hint, if you are on a PC, the name of the engine is on your keyboard...
