Space Monster+# 22+

Space Monster+ is a hack of Space Monster (U.S.: Alien Invaders—Plus). Enhanced "Plus" graphics – a recreation of a real Philips screenshot featured in publications from 1984 – were added. Philips based this screen on actual photos of the Space Shuttle Columbia being carried by a modified Boeing 747 transport aircraft. Other than the addition of background graphics and tweaks to the on-screen colors, the gameplay remains the same.

Space Monster+ was released on May 22, 2015. One hundred copies were made in the Videopac+ style. Although Space Monster never received enchanced graphics back in the 1980s, Philips did re-release it with fancier cover artwork – a treatment usually reserved for games getting a "Plus" makeover. This version of the cover art was tweaked for the homebrew release. It originally sold for 23 Euro (Videopac plastic cases were available for an extra fee).
