Ultramodern Bogeys (Patreon)

Although the setting is sci-fi, the game really has an eye firmly on the ultramodern and near future game, too.  No synthetic heroes, of course, but you can still have an EWOp, remotes, sentry guns and most every other option.

These new releases from Spectre Miniatures would be a fantastic set of Grunts in a near future "aftermath" setting.
