HL2DM Pro can feature multiple gameplays : HL2MP Original and ProMod are built-in but you can make your own gameplay using the built-in GDK (Gameplay Development Kit). As such, features sometimes apply only to regular HL2MP, Promod or other gameplay of your own. The 4th column named "Other gameplays" refers to all those gameplays. For those gameplay, a feature can be enabled or not depending on the gameplay designer. In this case, it is marked "Activable". If you can decide of the value when defining the gameplay, then it is marked "You decide".
