Rebellion make some of the most fun games I have played and I tend to play through most of them, in fact Zombie Army 4 was one of my favourites - wacky, creepy and a great difficulty curb.
The sale currently covers most if not all the biggest titles including:
- Sniper Elite
- (Nazi) Zombie Army
- Strange Brigade
as well as some older titles like Judge Dread, Battle Zone 98 Redux, Evil Genius, Arcas Path VR and Rogue Trooper Redux. The sale is offering up to 90% off but you can grab most all the games for peanut prices…

Strange Brigade is high on my list, I never did finish it while it was on Xbox Gamepass…
