I mean I downloaded the gallery and saw that there is go+, and saw lizard and bear scenes witch I didn't know that those exist, as for bear I let it catch me on unlocked door but I don't, know if you say sewers do you mean the section after escaping the crock mutant? And while I can look at the scenes from the gallery I want to get them the legit way.
The sewers isn't really an area you can explore, it is just an entrance. When you fix the omni tool and can scan the ship, there is a room that will appear on the right side of the map. When you enter that room, there is a panel with no power and you have to open a small vent and crawl inside to fix the equipment, you need to replace the red fuse on the left, repair the wire on the right, then replace the second fuse, then press the button on the panel on the right. If you get the combo correct, it opens a door in that room that leads to the sewer entry. The bear will spawn in that room at random times and you need to wait a few seconds without clicking on anything and you might need to enter or exit a few times for it to trigger. Don't attack the bear when it appears and it will capture Tali and drag her off to his lair.
The crock mutant is what I referred to as the Alpha. When he is chasing you in the halls, you need to fail to escape. After that, I think you need to use the seduction darts on them or just submit to him. I can't remember which option it is, but one of the choices will lead to Tali being captured in a game over + scene.
For the apes or varren game over + scenes, you need to let the turret heat reach 100 and then sleep in the med lab. Lose the fights with them and it should take you into the game over + scenes.
