I was going through the IL leader-board trying to beat all the times, when I noticed that the sewer levels ending was drastically different on GCN compared to PS2. This makes the level 20-30 seconds longer on PS2.

Here's videos of the 2 versions for reference.

I'm guessing this isn't the only level that's different but I'm not sure. And I haven't checked any other versions. Does this warrant a separate category for the GCN version?

It would be nice to also have leaderboards for individual levels: Mobnuts, Roman Beavers, Berserk Vikings, etc...

That way you could try to implement some riskier glitches like infinite jump

After a lot of glitch hunting I found how to do it! I'm interested to see if someone actually finds some use for this inside runs

I've tried to do some glitch hunting. Haven't found anything useful yet but maybe someone can come up with something with these. I've also made videos showcasing them.

You can push guards around after stunning them. You can also climb on guards by getting a bit higher than them.

You can climb many objects. You can also push guards up the same objects but I wasn't able to get a guard on the green recycling bin, since it requires more precise movement.

This is the only area I've found where you are able to do this. You can also move around on the platform. The door seems to break once you do this.

Probably the most interesting glitch. By getting the bomb to fall under the map once it keep spawning it there. It also explodes instantly after a bit. You can fix it with a platform or a ramp.

You can get the boat from one of the garages nearby. You are able to swim around for a bit until the counter hits 0

By jumping out of the boat before the cutscene you don't get the rocket launcher.

You can freeze the game by starting one of the side missions before the cutscene.

This isn't a glitch but you can shoot the valves and they spin. It doesn't seem to activate anything.
