Official Quakewiki Video - Quake - Aftershock for Quake - Introduction
We start this game on a promising foot. This level was made very akin to the original game's Introduction, meaning the difficulty paths are rather similar to those in the original game. Easy is still plain, Normal a bridge with Water, and Hard has a pit of Lava to jump over. The latter is a bit rougher, requiring precision to get across. Nightmare is also exposed to view, though to get down the player must use precision and drop to the right spot or otherwise risk being flung via a Wind Tunnel into a pool of Lava. All Teleporters lead to the Episode selection room, which is very plain compared to the original's, with all looking alike and being one room. Still, it is neat to see a new level exit, the Transporter.
