1P Game

The 1P Game (commonly referred to as "1P Mode" and "single-player") is the only single-player campaign mode available for play in Super Smash Bros.. In the mode, players progress through a series of 11 matches (interrupted by a bonus stage after every three matches), culminating in a final battle with the game's boss, Master Hand. The mode has been deemed largely forgettable, due to its static nature in which the player faces the same characters on the same stages in a fixed order during each playthrough). There are fourteen stages including bonus stages in this mode and players may choose their character and number of lives before the playthrough. The 1P Game was reworked into Classic Mode in Super Smash Bros. Melee and featured a number of improvements, among them the removal of the fixed match order.

Match stages

Stage 1

The first stage takes place at Hyrule Castle and pits the player against Link. Having many disjointed melee attacks and two projectile weapons, Link can be a hassle to approach. However, his lack of speed and maneuverability cause Link even more problems in approaching the player. In fact, much of Link's strategy consists of standing back, throwing a few projectiles, and waiting for an opening. The only terrain effect on the Hyrule Castle stage is tornadoes which appear randomly and tend to last between 10 and 20 seconds, and move randomly in a direction, although they may suddenly speed up and home in on a character. If caught, a character is held for about 2 seconds before being dealt 14% damage and thrown upward, resulting in a knock-out at roughly 100% depending on weight.

Stage 2

The second stage takes place on Yoshi's Island and pits the player against the Yoshi Team, comprised of 18 lightweight Yoshis. The Yoshis rarely attack and as they are lightweights, they are exceptionally weak and can be knocked out by almost any attack; sometimes they may even fall from the stage without any conflict from the player.

Stage 3

The third stage takes place in Sector Z and pits the player against Fox McCloud. Despite having speed unmatched in almost every aspect, Fox is a fairly weak foe. His attacks tend to have less knockback than those of other opponents. ARWING fighters act as the terrain effect in this stage. Occasionally ARWINGs will appear and commence fire at the players, causing significant damage. Also, if Fox or the player is standing on the ARWING as it flies offscreen, this may result in a knock-out; however, the ARWINGs tend to do barrel rolls or fly upside-down, which will essentially push the character off before it disappears from the screen.

Stage 4

The fourth stage takes place at Peach's Castle and pits the player against the Mario Bros., comprised of Mario and Luigi. In this stage, the player is accompanied by one, randomized ally. Mario is adept in close-range smash attacks while he makes use of a good, long range, and Luigi's combos, although less varied and versatile than Mario's, can be followed by his devastating Super Jump Punch. Peach's Castle has two main platforms, one on top of another. The bottom platform partially comprises of a block going left to right. On the top two corners there are two floating, inward-angled platforms that prevent people from being smash away too easily. It also has a floating bumper in the middle above the second platform of the stage. This bumper moves slightly left and right. It is harder to recover from this stage since the two floating platforms limit recovery to the top platform and there are no ledges.

Stage 5

The fifth stage takes place in Saffron City and pits the player against the Pikachu. Notorious for his high-priority aerials, good edgeguarding ability, and superb recovery, Pikachu is a versatile character with very few weaknesses. The player should never hastily approach Pikachu as its aerials can out-prioritize and out-range almost any move. The only terrain effect on the Saffron City stage is the door under a small platform around the center of the stage. This door occasionally opens, revealing a Pokémon at random, most of which deal damage to whoever is in its attack range. Some of these Pokémon can be knocked out, however.

Stage 6

The sixth stage takes place in the Congo Jungle and pits the player against Giant DK. In this stage, the player is accompanied by two, randomized allies. Giant DK has little knockback when attacked, while his own attacks can send opponents flying. Under the main platform of the stage is a Barrel Cannon which sidles left and right. If a character falls in the Barrel Cannon for too long, it will shoot them in the direction the arrow is pointing. Characters can also jump through the main platform, despite the inability to fall through it.

Stage 7

The seventh stage takes place in Dream Land and pits the player against the Kirby Team, comprised of 8 lightweight Kirbys. Each of the eight Kirbys sport a unique hat (with the exception of one, normal Kirby) corresponding to each of the eight starter characters in the game, and as such can make use of each character's neutral B attack. The terrain effect on the Dream Land stage is Whispy Woods, a tree in the middle of the stage, facing left, who occasionally blows wind towards a particular side of the stage.

Stage 8

The eighth stage takes place on Planet Zebes and pits the player against Samus Aran.

Stage 9

The ninth stage takes place at Metal Mario's Residence and pits the player against Metal Mario himself.

Stage 10

The tenth stage takes place on the Fighting Polygon Stage and pits the player against the Fighting Polygon Team, comprised of 30 lightweight Fighting Polygons.

Final Stage

The final stage takes place at Master Hand's Residence and pits the player against Master Hand itself. This stage stands out from most others in the game, as it can only be cleared not by knocking out the opponent, but by lowering the opponent's stamina to 0 HP.

Bonus stages

Bonus Stage 1

The first bonus stage is Break the Targets and takes place after stage 3, the match against Fox McCloud. It challenges the player to seek and destroy the ten targets placed throughout the stage within a 2-minute time limit.

Bonus Stage 2

The second bonus stage is Board the Platforms and takes place after stage 6, the match against Giant DK. It challenges the player to seek and step on the surfaces of the ten platforms placed throughout the stage within a 2-minute time limit. When a platform has been boarded, the otherwise red light it emits will become blue.

Bonus Stage 3

The third and final bonus stage is Race to the Finish and takes place after stage 9, the match against Metal Mario. It challenges the player to descend five floors and reach the exit of a Fighting Polygon outpost within a 2-minute time limit.
