  We find new classes of AdS_4 solutions with localized branes and
orientifolds, both analytic and numerical. We start with an Ansatz for the pure
spinors inspired by a recently found class of AdS_7 x M_3 solutions in massive
IIA; we replace the AdS_7 by AdS_4 x Sigma_3, and we fibre M_3 over Sigma_3 in
a way inspired by a field theory SU(2) twist. We are able to reduce the problem
to a system of five ODEs; a further Ansatz reduces them to three. Their
solutions can be bijectively mapped to the AdS_7 solutions via a simple
universal map. This also allows to find a simple analytic form for these
solutions. They are naturally interpreted as twisted compactifications of the
(1,0) CFT_6's dual to the AdS_7 solutions. The larger system of five ODEs also
admits more general numerical solutions, again with localized branes;
regularity is achieved via an attractor mechanism.
