Brinstar
Hive Room
For all categories except low% you will want to take the path shown in this video. In low% you do not grab the missile on the left, and with some hard mode categories you may find yourself here with Long Beam which trivializes this room. This setup has a high chance of gathering all the bugs from the 2nd and 3rd hive to follow you to the lower half of the room, leaving you the freedom to cross the upper half without too many issues. There is a random chance that the bugs will still fly up in your way and ruin the room, that's just the randomness that makes hive room such a troublsome room.
Brinstar Super
Any%
This is the only super missile located in Brinstar, this trick is useful because allows Samus to take this tank faster than the intended way, this trick is slower than doing the zebetite skip without it, but it makes Tourian much safer, also with this missile, we don't need to do the zebetite skip, we have almost enough missiles to finish Mother Brain room if we farm 2 more missiles in the room. (Red rinka missile drop rate is increased in that room)
To perform this trick, Samus has to store a speedboost, and do series of tight platforming, and then Morph Ball Shinespark (ballspark) to the left.
