MAP4

MAP4 is a Single Player level found in QuakeMap starting from version 2.0. This level is referred to in-game as "No Name", much like the rest of the QuakeMap levels. This level was designed to show the duplication feature of QuakeMap, meaning the level and its geometry is highly symmetrical.

While this level has an exit leading to Introduction, it is impossible to reach due to a broken Teleporter that overshoots the player into a pool of Lava.

Walkthrough
You spawn on a medium-sized platform at the edge of a room mostly filled with Lava except for a pillar in the middle of said room. This level is highly symmetrical, featuring the same basic layout of pillars and Lava. To the left is a Elevator leading to a pillar that in turn, if climbed, allows the player to exit the level. Both the Elevator and pillar platform are too high to climb out of the Lava from, meaning another way around must be found. To your right, across a pool of Lava, is a doorway. This doorway is the only safe location from Lava, the jump must be made exactly to avoid not overshooting or undershooting. However, the platform the player is on is too low to make a proper jump, so instead turn to your right to look at the pillar.

Jump to the right side of the pillar, the more open portion of it, and then follow the circular staircase to the top. This in turn triggers the starting platform to become an Elevator, continually moving up and down. Jump back to the starting Elevator, then turn right to make the timed jump across to the doorway now that you are high enough to reach it. Follow the thin platforms to your right to reach the pillar straight ahead, then head up it to hit a Wind Tunnel that pushes you beside the doorway leading to the next room. You are currently on a Platform, but it is quickly descending. Move to your left quickly to get to the doorway proper, though this will in turn trigger another Platform to your left to start descending. Turn to your left while heading onto this Platform, then quickly use it to jump to another Platform straight ahead that will start descending. Jump to the next Platform that will start descending straight ahead, then turn left to jump to the pillar. To your extreme left is a doorway leading to the final room, but it is too far to reach. Instead, the player can jump forward to reach a Teleporter that should take them to a platform near the Elevator. Note however that the acceleration the player needs to move at causes them to be automatically pushed in the Lava, making it impossible to use the Teleporter and thus complete the level.
