Coming soon: Quake Combat+, a refinement of Quake, SMC v5.3, and Quake 1.5 aiming to provide the ultimate Quake combat experience without straying too far from the original design to retain compatibility with the hundreds of great custom-made user maps.
One of four new powerups - Rapid auto shotgun upgrade. This is a very rare backpack drop and only lasts for the current level. It makes the starter shotgun a rapid beast, perhaps even better than the double barrel. Enjoy it while it lasts if you get lucky enough to find one.
