Four-way Cannon Cavalcade

Four-way Cannon Cavalcade is the fifth Challenge Act of Crisis City Act 2 in the console/PC version of Sonic Generations. It is unlocked after clearing every Stage in the modern era and is playable only as Modern Sonic.

Overview
This challenge act takes place in a modified version of the section that is normally reached after the fourth Point Marker in the original stage. It features nearly the same path layout shown in that mentioned section, but now the player has to use a network of Four-way Cannon to proceed forward unlike in the original version which resorted on Springs to cross some parts of the stage automatically (like crossing the skyscraper part at the start of the stage), in addition to other parts in this challenge act that the player also needs the Four-way Cannon to reach higher areas. The networks of Four-way Cannons in this challenge act do usually have moving Spiked Balls in them, so the player should avoid getting in contact with them or the player will fall. In this challenge act, all of Iblis's Minions appear, and there is just one Point Marker in the whole challenge act.

Description
As mentioned above, this stage's start point takes place at the same location found past the fourth Point Marker in the Act 2 version of Crisis City. However, by using the Spring in front of the player at the start point, the player will not be sent directly to the peak of the skyscraper, but they have to use a network of Four-way Cannons to reach it. The easiest way to cross this section of cannons is to follow the direction the path of Rings of each Four-way Cannon leads to, and wait for the moving Spiked Balls to move away from the path. After going up from the last Four-way Cannon of this network, the player should reach the peak of the skyscraper by a Dash Ring. A combination of this Dash Ring's boost and a Jump Dash are enough for the player to reach the highest route of the skyscraper which has a yellow Time Bonus along it. However, if the player chooses to not to use this route, they will have to cross the route of Iblis Biters below it instead. These two routes are actually in 3D, and the player can move freely in them so it is better to watch out not to go down to a Bottomless Pit.

After crossing either of the mentioned paths, the player will reach a route filled with nine Explosion Traps, and will have to cross this path using a series of Four-way Cannon placed in a row. However, the player must be very wary when using the Four-way Cannons as the Explosion Traps there (especially on the ground) burst very quickly. After this route, the player will encounter an Iblis Biter and an Iblis Taker that bursts quickly from the bottom of the screen to attack the player. The player can use this Iblis Taker to reach a yellow Time Bonus found on a small platform above them. After these two Iblis's Minions, there is a wide fiery area with three Iblis Takers that constantly attack the player, with the player's only way to cross them is to use the moving platforms above the area to go up and proceed forward.

After crossing the first and only Point Marker in this act, the player will be sent to a Bottomless area with the only way to cross it is by using the network of Four-way Cannons there which also include some moving Spiked Balls in them as well. The player will have to follow the direction the green arrow that appears in each Four-way cannon points to cross to the other side (However, between the last five Four-way cannons there is a yellow Time Bonus so the player should go to the opposite direction the middle Four-way Cannon's green arrow points to in order to get it). After this network, there will come a section filled with Spiked Traps on the ground and Explosion Traps on the ceiling which the player has to avoid by using an another set of Four-way Cannons. In the same location, there is also a blue Time Bonus that can be collected from the ceiling. The rest of the challenge act from this point is crowded with many Iblis Worms, Explosion Traps and Spiked Traps. So, the player must balance his movements with the Explosion Traps' bursts, attack the Iblis Worms, and use the Four-way Cannons along the way to reach the Goal Ring in time.
