SF4 Combo System Exploration, Part 2

November 24th, 2009 Leave a comment Go to comments

Having investigated SF4 a little further, it’s apparent that the entire combo engine is based on a list of special properties arbitrarily assigned to various moves. In order to predict exactly what will combo into what, we need to put together a comprehensive chart of these traits by testing every attack.

Here’s an incomplete list of specialized attack properties i’ve encountered while experimenting primarily with Ryu, Zangief, El Fuerte, and Ken:
– always creates a juggle state against a grounded opponent
– always creates a juggle state against an airborne opponent
– only creates a juggle state against a non-reeling airborne opponent
– only creates a juggle state against a reeling airborne opponent
– resets the juggle counter without creating a juggle state
– possesses an inherent juggle potential of __ (some integer)
– knocks down on counterhit
– always renders opponents invincible
– renders grounded opponents invincible
– renders airborne opponents invincible

When an opponent gets knocked down through conventional means, they can only be juggled by an attack with a juggle potential of one or greater. After they’ve been juggled once, they can only be juggled by an attack with juggle potential of two or greater, and so on. Generally whenever an attack creates a juggle state, it also resets the juggle counter.

For example, the first hit of Ken’s MP Shoryuken has no inherent juggle potential and knocks down on counterhit. The second hit possesses an inherent juggle potential of one.

The first hit of Ken’s HP Shoryuken only creates a juggle state against a non-reeling airborne opponent, knocks down on counterhit which satisfies the airborne condition for creating a juggle state, and has no inherent juggle potential. The second hit only creates a juggle state against a reeling airborne opponent and has no inherent juggle potential. The third hit has a juggle potential of one.

The first hit of Ken’s EX Shoryuken has no inherent juggle potential. The second hit has an inherent juggle potential of one and resets the juggle counter without creating a juggle state. The third hit probably has a juggle potential of one, but might have a juggle potential of two. The fourth hit probably has a juggle potential of two. At least one of the last two hits has a juggle potential of two, because EX Shoryuken juggles once after anti-air MP Shoryuken hits twice.

The first hit of Ryu’s j.MP always creates a juggle state against an airborne opponent and has no inherent juggle potential. The second hit of Ryu’s j.MP has an inherent juggle potential of one.

Ryu’s Shinkuu Hadoken has an inherent juggle potential of five and the last hit renders grounded opponents invincible. Ryu’s Metsu Hadoken has an inherent juggle potential of eight and the last hit renders grounded opponents invincible.

All normal moves render airborne opponents invincible. As far as i can tell, all sweeps always render opponents invincible.

Anyway this is clearly too much information for me to compile alone, so it would be nice if everyone contributed their findings. If not, i’ll continue posting whatever i happen to find as i make my way through the cast.

    Most special moves create a simple knockdown where the opponent is invincible to attacks which have zero juggle potential. You need to use an attack with a juggle potential of one or more to combo after them.

    Some special moves create a special knockdown state which we’ve been calling a “free juggle state” and those allow you to juggle with anything you want. The last hit of Sakura’s EX Hurricane Kick and Gouken’s EX Palm launcher both create free juggle states.
