Launchers are the means of getting airborne off the ground.Some will require manual input for a proper launch. If it seems too hard, then one can buy the Time Warp from the Black Market to assist with launch. Mostly that's all they do, but there is one exception...
Empty: Unlocked by default
Coil: Part of the starter set. Is good, cheap, and gives a good lift for its price.
Slingshot: Part of the starter set. Has a really good lift if used correctly. ACTIVE LAUNCH
Tilt Cannon: Part of the starter set. Slightly frustrating to use. ACTIVE LAUNCH
Grenade: Part of the starter set. Always has great lift, if used correctly. ACTIVE LAUNCH
Russian Roulette: Part of the starter set. Use at your own risk, it is highly prone to failure. ACTIVE LAUNCH
Catapult: Comes out of a card pack. Do not use if you can't spam keys. ACTIVE LAUNCH
Explosives: Part of the starter set. Gives decent lift.
Powder Cannon: Part of the starter set. Has great lift, but it is hard to master the launch sequence. ACTIVE LAUNCH
Steamshot: Comes out of a card pack. Great lift, but contains an extremely volatile launch sequence. ACTIVE LAUNCH
Bazooka: Great lift, but is hard to master the launch sequence. ACTIVE LAUNCH
Launch Pad. Has the most ironic name ever. Functioning like a realistic launch pad, it does not assist with launching the penguin but supplies 20% extra fuel. Obtained by way of the Black Market.
Alien Bait: Part of the starter set. It's great for light bodies, but otherwise garbage. ACTIVE LAUNCH
Nuclear Reactor: Part of the starter set. For novices, it's everything they wished for.
Orbital Cannon: Comes out of a card pack. It is one of the best launchers, and is better than the Big Bertha until upgraded to level 6 and above. ACTIVE LAUNCH
Big Bertha: Comes out of a card pack. Nearly as good as the Orbital Cannon, and a launch sequence similar to the tilt cannon. After level six, the Big Bertha is better, but costlier. ACTIVE LAUNCH
Omega Coil: One of the Six Omega Parts. The Very Best like none other. Has extremely great launching power, and works just like the regular coil.
