Many Metropolice posters were to be seen around City 17, but were removed when the development team thought that the Combine did not need to rely on subtle messages to achieve their goals. Three posters, designed by Randy Lundeen, are known of: one involves the Consul, an early Citadel, early CPs (such as Combine Guards), and the slogan 'It's great to be part of the greater good'. Two other posters, again including Combine Guards, bear the ironic slogan 'They're here for you'.Some of these posters are featured in WC mappack maps, when propaganda was still an important storyline tool for the team.
Originally, the Civil Protection was to be named 'Metropolice', a name that survived in the CP entity, 'npc_metropolice'.
