Worms and Reinforcements United

Worms & Reinforcements United (commonly known as Worms United) is a combination of the original Worms and Worms Reinforcements for MS-DOS. It combined both onto one CD-ROM, and the original retail release also included a 1.44" floppy disk with extra landscapes.

In 2011 it was released onto Steam and in 2012 onto GOG.com, running in the DOSBox emulator. (The Steam release is just titled Worms.)
