S.L.A.I.: Steel Lancer Arena International

The game's main story line takes place in 2071, in a future where the sport of "rumbling" has taken precedence. Players called "wire-heads" compete by piloting SVs, a variation of the mech, in specially built arenas in seven real world cities such as New York City, Tokyo, and London. Each city has eight standard "rankers", ranging from categories D-A which describe the overall difficulty and whether they compete during the day or night. Upon beating all 56 of these Rankers, players can then battle against each city's Regional Ranker. After beating these seven, they are allowed to compete for the Third, Second, and First Ranker, officially making them one of the best players in the world. During this quest, players will become part of an investigation trying to find a serial killer who starts killing other wire-heads, with the plot moving as rankers are defeated.

Like in Phantom Crash, there are several (fictional) Companies in SLAI.

Kojima – Founded 1969 as a machines plant in old Tokyo. Began constructing SVs in the early 2020s. Their SV is the Ultralight "Proton", the successor of the "Photon" from Phantom Crash. The company name is also a reference to the main producer of the game, Ichiro Kojima.

OMSK – A former Soviet bureau formed in the 1980s (1950 in the Japanese Site). OMSK entered the civilian market in 2027. Manufacturers the lightweight, long-range SV "кит" (Russian for whale).

Ventuno - The Italian automobile company, founded in 2001, produces the Carro (Italian for wagon). The mid-ranged Carro has the most balanced specs out of all of the SVs.

S&V Ma. Fabrik – A German robot company founded in 2016. S&V's Scoobie, the shortrange/melee-type Zwerg (German for Dwarf) has unique melee weapons like the EMP-Fist.

American Stars - The American conglomerate that has been making some of the world's leading SVs from 2012 to 2071. It is the supplier of the heavy Hartman SV.

Player – represents yourself in the Story mode of gameplay. You can determine your gender when you first start by choosing among the free Lo-Tek models, some male and female. Later in the game you can purchase different "personas" from the IDOL shop.

Knocker – A very minor character; he is your virtual daemon guide when you first join HAVEN. He stays with you until you switch his Chip for a different one. If your chip shuts down, knocker comes back until you get a new chip.

DD & JJ – When you first enter Hard-Wired, where you go to enter rumbles, you run into this curious duo. As a freelance internet blogger, DD has been having trouble getting hits on her site, and is in debt up to her knees from the purchase of her new "Edge" series persona. JJ is a dog IC (Intelligent Chip) that serves as the main editor of DD's blog site. The player agrees to have DD and JJ report on their progress.

Embryo – A rumbler on the God Mode team. When you take the FIRA exam in the beginning, Embryo is one of the Wire-Heads you rumble against. He changes his persona throughout the story and gets stronger alongside the player. He has a sheep chip named Anima.

Lynx – The third place world ranker. Later in the game he becomes the second world ranker. He has a bird chip named Helix. He is the leader of the God Mode team, which is made up of himself, Skeln, Sin, Embryo, and Flint.

Bogeyman – The first place world ranker. He has a fox chip named JOL.

Hot Rod – The second place world ranker. He has a monkey chip named Cool Cod. He dies in real life early in the story.

Lucas – The third place world ranker after Lynx takes over the second place. Has a unicorn chip named Chani.

Gameplay consists of free-for-all style combat, pitting the player against computer controlled SVs. The object of the battle is to defeat every "rumbler" that appears in the arena, though this goal is made difficult by the fact that defeated SVs will return while you are still rumbling. Once every SV has been defeated, the Ranker of that arena and particular "Class Level" will arrive, made apparent by a unique statement appearing in the dialogue box at the top of the screen. Once the Ranker has been defeated, the player may either leave through an entrance gate, or continue play against previously defeated Wire-Heads. Each arena has several destructible targets which can be destroyed for money known as "Crypto Credits". During the course of a rumble, support crates, known as "Cubes", will be dropped into the arena at designated zones. Among the Cubes, there are three varieties: Green "Ammo" Cubes that replenish ammunition levels, blue "Crypto" Cubes that add to the player's winnings, and last being red and white "Armor" Cubes which restores the SV's armor levels and repairs damaged weapons.

SVs come in five varieties. Protons, KHTs, Carros, Zwergs, and Hartmans. Three additional SVs, Molniyas, Arditos, and Elints, can be purchased from Wild Machines after completing the story. Each SV can hold up to four weapons, consisting of two arm weapons and two shoulder-mounted weapons. These include machine guns, swords, missiles, lasers, chainsaws and many other unique armaments. A particular sword module called a "Plasma Pulverizer" can disable an enemy's Optical Camouflage for a limited amount of time when they're hit with it. SVs may also be equipped with several option modules. O.C. or, "Optical Camouflage" will allow an SV to temporarily become invisible. You can purchase better models that have a longer run time and faster regeneration time. SV's can also be decorated with paint and decals. Also, you can buy certain items that look like an envolope called "stocks". They have a different name on each one representing a different company. The value of these items fluctuates over time so the player must sell and buy them at the right time.

Of particular note are the chips that accompany the player throughout gameplay. In the game's story, chips are responsible for actually operating SVs while players remotely control the action from special computer terminals. Represented by animals, they each have distinct personalities and can gradually learn skills that enhance the performance of SVs in a style similar to role playing games. Like SVs, they are capable of being destroyed upon receiving too much damage in a rumble, and therefore must be regularly maintained.

Certain rumblers called "Crashers" that can enter or exit a match at any time and are often represented by a blue health bar. They are usually very dangerous, have lots of health, and can deal extreme amounts of damage in little time. Crashers are, in reality, Rankers from both different locations and of different, sometimes higher, ranks.

Outside of battle players may perform a variety of tasks via a stylized menu interface that represents the city's computer server. Included are a variety of shops for rumbling-related services, including stores to buy SVs and parts, a "beam-port" that allows players to travel between cities, and an official Rumbling area where players enter battle.

In the world that you play in, known as HAVEN, there are several different locations ("stores") that you can visit. You can change between stores as often as you want. However, 3 of these stores give you an option for skipping ahead to the next day (marked with a †).
