The company, 'Sample Fuel', has a free 'LITE' bundle of six of their products for 'Halion Sonic SE'.
There are some great sounds in there, and if you like getting creative, plenty of sound design options available.
Even if you don't own Cubase/Nuendo there is a link provided so you can download 'Halion Sonic SE' (free) for use outside of Steinberg products with little fuss.
