The Combine are an interdimensional empire from the Half-Life universe. Their technology and infantry are frequently seen in VenturianTale, though their canonicity is vague.
- The battle of Skittles- A war Jordan and Isaac fought, which was to protect the skittles.
- Unnamed Combine Fight: A fight against the Combine and Daleks (With other enemies, such as the Weeping Angels)
- It is possible that the 7 Hour War indeed happened (along with the Portal Storms/Cascade), but the Combine were somehow defeated. This is evident by possible reverse engineered Combine technology featured in maps, and SWAT consisting of Combine soldiers.
