Street Fighter V makes tweaks and adjustments all across the board, from the Variable System and it's 3 mechanics to many small changes that differentiate it significantly from other games in the series. I would highly reccomend watching this video to get a grip of both the bigger and smaller mechanics, but below we'll detail the biggest ones for reference:
V-Gauge
V-Skill
V-Reversal
V-Trigger
Stun Bar
Critical Art
Crush Counter
V-Gauge
The V-Gauge replaces the Revenge meter from Street Fighter IV. You can fill it up in two different ways. The first is by taking damage (blocked or connected), much like in SFIV, and the second is through V-Skills, which are described below. The size of your V-Gauge differs from character to character, ranging from 2 to 3 stocks in the characters that have been announced thus far. This is for balancing purposes, and characters with more bars take longer to fill up. The V-Gauge can be used for doing V-Reversals and activating V-Trigger. The V-Gauge does not carry between rounds.
V-Skill
V-Skills are moves unique to each character, performed using medium punch medium kick, that help build your V-Gauge with their use. They do not cost anything to use, and are intended to provide an offensive alternative to gaining V-Gauge meter in comparison to just taking hits. Some V-Skills need to connect in order to build meter.
- Ken - Quick Step - Ken dashes forward a short distance, which he can then cancel into a step-kick or other moves to gain forward momentum.
- Necalli - Culminated Power - Necalli pounds the ground, creating an explosion on the ground at a distance the player can select using the joystick (left/close, neutral/mid, right/far).
- Vega - Matador Turn - Vega performs a dodge attack with the option of cancelling into a counterattack that knocks down.
- R. Mika - Mic Performance - R. Mika pulls out a microphone and starts giving a monologue, powering up her normal and special throws more and more as it's held down. R. Mika can absorb one hit of damage while in this mode, and can let go of the V-Skill input at any time to cancel the speech and throw the mic at the opponent.
- Rashid - Front Flip and Rolling Assault - A neutral V-Skill input will launch Rashid into a flip that can be cancelled into a divekick using a kick, whereas pressing down with the V-Skill input will cause Rashid to do a roll forwards into an upkick.
- Karin - Meioken - Karin lunges forward with a palm strike that can nullify projectiles and knock down the opponent. This move can be charged to receive better hit and block properties.
V-Reversal
V-Reversals are essentially like Alpha Counters from the Alpha series of SF games, and at the cost of 1 stock of your V-Gauge allow you to perform an instant reversal while in blockstun. This is performed by holding forward and pressing all three punches with every character except Cammy, who activates it through holding forward and pressing all three kicks. They also vary slightly between characters, but mostly serve the same purpose.
V-Trigger
V-Triggers are powered-up states, similar to the Instinct system in KI or install supers in other fighting games, activated by pressing both heavy punch and heavy kick when your V-Gauge is full. Once activated, the bar turns into a timer of sorts and slowly depletes over time and for some characters through the use of specials. If you are comboing your opponent with a normal or certain specials, you can use the V-Trigger as a cancel to extend your combo as well. Each character's V-Trigger offers them unique bonuses:
- Ken - Heat Rush - Ken's special attacks get powered up via an increased number of hits and the distance they cover.
- Necalli - Torrent of Power - Necalli powers up into a new form permanently for the rest of the round, featuring new frame data, a new critical art, and new combos/moves.
- Vega - Bloody Kiss - Vega quickly throws a rose at his opponent, and upon hit Vega hits the opponent with a combination of brutal slashes. This can be done from the air, or while crouching as well.
- R. Mika - Nadeshiko - R. Mika can call her tag team partner for assistance in 3 different variations: a body splash from above (neutral input), dropkick from the front (back + input) or a dropkick from behind (forward + input).
- Rashid - Ysaar - Rashid throws out a whirlwind that moves it's way towards the opponent, but also enhances the velocity of any moves Rashid does that move him forwards.
- Karin - Kanzuki-Ryu Guren No Kata - Karin gains access to the highly versatile Guren Ken attack, which can be immediately cancelled into an overhead, sweep, flying throw, several strikes or a backdash.
Stun Bar
You no longer need to estimate how much stun your character has, as there is now a meter below the health bar that indicates your stun.
Critical Art
Critical Arts replace Supers but are pretty much the exact same thing. The Critical Gauge now has 3 stocks, in comparison to the 4 in SFIV. Another difference is that you can no longer gain meter from whiffing normals, and must connect an attack to gain meter.
Crush Counter
Some moves upon counterhit will put your opponent into a stun state that lasts a bit longer than usual, akin to Fatal Counters in various Arc System Works games.
