Challenge Acts include regular stages and custom challenges (except for Hard Mode)

In the configuration menu, you can switch between vanilla and custom physics (improves steering).

A cool level pack for SXSG! But I probably found an unlisted glitch in this mod.

In the level of "Air Fleet" (Westopolis Zone Act 2 Challenge 1), the player needs to beat the level under the limit. However, the checkpoints in this level seemed to break the Time Attack system. When Shadow touches a checkpoint and then dies, Shadow will respawn at the last checkpoint correctly, but the time will reset to 0'00". And you may beat the level in 1'00" in a easier way.

I think this is unintended...?

Challenge Acts in Shadow Gens are designed without checkpoints. Respawning at the checkpoint will always result in a time/countdown reset.

Since some main stages take more than 1 minute to complete, I chose to keep the checkpoints and not set strict time limits.

Fine, and here comes another glitch:

In Death Ruins(Prison Island Zone act 2), the stage loads normally, but I can't see the background and it only loads fog shaders. However some levels are at the bottom of the level, so this caused this part becomes extremely difficult for me, due to the lack of visibility. I can only see the outline of the level with Chaos Control

Not entirely sure why, but trying to access the configurations for this mod crashes HedgeModManager

Chaos Island Challenge act (The Ark: Reach to the goal) lacks a pulley at the first checkpoint, making the level unbeateable

Thank you for reporting. Sorry to disappoint.

At the moment the mod is very buggy, and most likely nothing will be fixed, just like in last year's "Heroes Stage Pack".

I was able to enjoy some levels, but generally, with modern physics, it's not very enjoyable to play. It turns out to be some kind of gaming product!

SeasideRanger @ 2026-10-24 10:36:51

Updated Bug List:

- The Ark (Challenge Act), has broken Pulley object making it impossible to complete

- Cryptic Castle (Circus Park: Act 2), near the Goal Ring, at 120 FPS the invisible wall appears too early, making it possible to complete only at 60 FPS and lower

Sorry for the inconvenience.

This is the first time I actually play Shadow 05 stages, and my god they are awful lol (it's not your fault at all, they are decent ports)

But I do want to point out the lack of screenshots here tho....
