Championship Mode, in a nutshell, means hot tournament action and match replays that let you watch the best of the best. Championship Mode goes live for bothPS3 and Xbox 360 on Friday, April 24, and it comes entirely FREE.
For anyone that wants more than will fit in a nutshell...
Tournaments:
The tournaments offer a new take on classic SFIV competition. They are broken out into 5 different levels, which means everyone can participate and find a goodchallenge without getting blown out of the water or bored. You score Grade Points (GP) for tournament wins, and as your GP total grows, you'll becomeeligible to enter into more exclusive tournaments. Winning tournaments will also net you Championship Points (CP). The CP work basically like "prizemoney" up for grabs in the tournament. The higher the GP skill of the players in a particular tournament, the bigger the CP prize!
In true tournament tradition, character selection is double-blind. With the CP purse on the line, you won't be able to see who your opponent has pickeduntil you've both made your choices, and the battle is set to begin.
The tournaments are run according to a standard type of single-elimination bracket, but your opponents are generated dynamically. This means the matchingsystem will automatically match you with a player of your skill level participating in that tournament type, so you don't have to wait around. Since thetournaments are already seeded by player strength, you're assured quality opponents at your same skill level, as fast as possible. If you can advancethrough the rounds to take a top placing, you'll score GP and CP. As your points increase, you're eligible for tournaments with increasingly strongopponents.
--SG Championship (SUPER GRADE): 5 rounds long. The highest grade championship in which only top players can participate.
--G1 Championship (GRADE 1):5 rounds long, for advanced players
--G2 Championship (GRADE2 2): 4 rounds long, for intermediate players
--G3 Championship (GRADE3) 3 rounds long, for beginners
--FREE Championship (Free Grade): 4 rounds long, open to anyone regardless of their level.
The tournament system is set up to reward you for participating. At G3, you actually score a point even if you get knocked out in your very first match. At G2,you don't gain points for a first-round loss, but don't lose any either. Similarly, you never lose points by participating in the FREE ranktournaments. Only in the top G1 and SG tournaments is it possible to lose GP, and even then you only ever lose 5 points for a first-round loss.
One of the best things about the new mode is that can play in tournaments in just the same way you can use the "arcade request" feature, soyou're free to play in arcade mode while waiting for your next tournament challenger, who will be chosen automatically based on your rank.
Last, but most certainly not least, disconnecters, aka pullers, aka ragequitters, your days are numbered: If you disconnect during a match, the system willalso dock you your progress in the tournament, so pullers will never be able to advance into the higher ranks of tournaments. What's even more fun is thatthe system also happily displays your disconnect percentage, so if you've got a bad habit, it's right there for everyone to see.
Replays
Replays are generated straight from the Championship Mode tournaments. The top 5000 Championship Point leaders will be given the option to upload a replay,which are then available for anyone to watch. Everyone on both X360 and PS3 will have be able to watch any of the replays on their platform, but there are alsosome system-specific extra features on the replays:
On PS3, viewers can watch your replay and vote in real time according to characteristics like "beautiful" or "funny." For the nerds, youcan vote once every 30 frames (that's 2x a second!), although there is a cap to avoid total vote spamming. Replays will be ranked according to theuser-submitted reviews, making it easy to find the flavor of replays you want to see.
On X360, you can't vote on the matches, but you can watch and then save a number of your favorites. While watching your saved matches, you'll also havethe option to turn on input commands (just like the Training Mode option), so you can see the gritty details of exactly what button and joystick inputs the topplayers are using to win.
And just for good meansure, the full press release is below:
