Hi there,
Thanks for playing Bioshock! I made it over the course of several years for CSS
The reason there are no stage 4 videos is I dont believe the latest cs:s release has be beaten except in private matches (although I could be wrong).
I'm currently working on v6, for cs:s. The whole map has been redone, largely from scratch, and many problem areas have been redesigned. It plays better, looks so much better, and introduces a lot more balance.
First for those who dont know:
-The map has 2 difficulty settings, that automatically apply. The default is Hard. 3 consecutive losses turns on easy mode, until there is a win for humans.
Anyway, I'll clear up as few things about the map since I'm here:
-The "Freak" is a Big Sister from Bioshock 2 (a Little Sister who has grown up). She appears randomly on a players location, on rounds where easy mode is disabled. Standing in the purple light does not hurt the player. Touching the Big Sister is what will kill the player, The light is a clear warning to steer clear.
-Each plasmid has a varying number of uses depending on if the round is on easy or hard difficulty. I can't remember them off the top of my head, but assume that easy mode plasmids have 100%+ more uses.
-Plasmids dont affect the Bosses. Even if they did, you shouldn't need to use them. The bouncer exists to trim a few players off the team for the final hold, not for players to have a real challenge beating it.
-Sonic Boom is as balanced as the other plasmids in its function. Unlike most maps with items, where if you dont have one you might as well not be playing, their effects are pretty minimal: Ignite, freeze, slow+damage, small knockback and no AOE. They exist to make things easier. You shouldn't *HAVE* to use any one of them unless you have a particularly weak CT team, or an early trim puts pressure on the humans later.
Round 4:
There are no guides for round 4. It is hard. What you must do is defend spawn, and backpedal for several minutes, while ~8 players enter the tower room, and hunt out the 8 bomb parts (3 wires, 4gel, 1 nitroglycerine).
-These parts must be taken to the bomb in the crawlspace of Kyburz' office (there are visual directions).
-This bomb must then be taken to the center of the tower room.
-After this, players are teleported to Ryans Trophy room, where they take an elevator to the boss.
-The boss is damn hard. And has 2 stages:
Stage 1: He has a combination of solid lazers _to knock you to your death, and push& pull attacks. Easy to deal with, chat and particles denote what attack he will use. Boss himself is static. Just shoot him continuously.
Stage 2: Never stop running if you can't see him. Boss spawns on players like the Big Sister mentioned above. Instant death if you touch him. he spawns ice around him then that will harm and freeze you in place for a few seconds. Shoot him whenever hes kneeling.
-After boss, a 2 stage hold after some tunnels. You defend the escape pod (Bathysphere), and ride it to the end. For the bad ending.
Alternate stage:
Stages 1-3 each have a hidden emblem in them. Shoot them all until they break, and round 4 will have some significant changes. It will play out until you reach the boss. After that, you can work it out for yourself
I hope this was useful. If you ever want help with the map, or have suggestions, or are playing and want me to come looksies, add me on steam (my account is linked).
Best wishes,
