We develop the helicity formalism for spin-2 particles and apply it to thecase of gravity in flat extra dimensions. We then implement the large extradimensions scenario of Arkani-Hamed, Dimopoulos and Dvali in the programAMEGIC++, allowing for an easy calculation of arbitrary processes involving theemission or exchange of gravitons. We complete the set of Feynman rules derivedby Han, Lykken and Zhang, and perform several consistency checks of ourimplementation.Comment: 22 pages, 10 figures, uses JHEP3.cls and axodraw. Some minor clarifications in the text, version to appear in JHE
