The Geophysical Fluids Modeling Framework (GAME) is a global hexagonal C-grid non-hydrostatic dynamical core. The aim is to combine the best aspects of ICON and MPAS.

A very brief scientific overview of the model can be found here. A more extensive theoretical derivation can be found in this German textbook.
Sample plots
Ullrich test
The Ullrich test [doi]
is a standard test case for the adiabatic part of dynamical cores of global atmospheric models.
Held-Suarez test
The Held-Suarez test [PDF] examines a dynamical core's climatology under a very simple radiative forcing, which depends only on absolute latitude and height. The test is usually run for 1200 days, with the first 200 days being used as a spin-up period.
