Worms Blast

Game

The gameplay is similar to that of Puzzle Bobble/Bust-a-Move, but with several key differences. There is a hexagonal grid of coloured blocks at the top of the screen, while the player's character sits on a boat floating in water. Unlike Puzzle Bobble, it is able to move side to side. There are multiple weapons that can be used, however the only weapon the player has to start with is a bazooka. As with Worms, holding down the fire button increases the power behind the weapon's launch, affecting how far it will travel. It is possible to fire the bazooka (and some other weapons, such as the grenade and dynamite) in an "arch", allowing players to reach difficult areas.

Shooting blocks will have one of two effects:

(Weapons are affected differently by other blocks. This is covered further below.)

Single-player puzzle mode

In this mode, the player travels around the world (in a method slightly reminiscent of Capcom game Pang) completing puzzles. Again, differing from Puzzle Bobble, missions are usually more complex than simply clearing the blocks off the screen. Some may require the player to perform certain tasks (such as shooting down space ships made of blocks, or avoiding a snake-like series of blocks moving around the screen). The missions become progressively harder. The aim of the game is to reach the volcano in the centre.

Unlike Puzzle Bobble, there are no walls in single-player mode. If the player fires a weapon off the screen, a heavy object (such as a cannonball, weight or fridge) will fall onto his or her character, reducing the player's health.

Unlockable characters can be earned by reaching certain points on the map. It is not necessary to complete every puzzle to reach the centre, however this is the only way to unlock all three characters.

Multiplayer

In all Multiplayer modes, the barrier separating the two players will open periodically. Players can use this opportunity to shoot at each other with their Bazooka in an attempt to reduce their health and ultimately knock them out of the game.

Single player

Characters

The game is played with nine characters (three of them must be unlocked) and most of the characters are actually animal weapons from the original Worms. Every character has a unique boat, and differing stats for Amount of Health, Boat Speed, Speed of Aiming Reticle, Turning Speed, and Boat Size.

BLAST mode

In Multiplayer mode, when standard blocks produce a chain reaction (more than 10 blocks must get destroyed), player should collect the falling fruits (every block becomes a fruit after being destroyed). If a player collects these fruits (10 or more) one letter of BLAST word on the bottom of the screen will get coloured. Each colour represents a letter:

When all letters are filled, BLAST mode begins. All the blocks on player's side of the screen vanish and targets begin to fall on parachutes. Shooting a target produces a Weapon Crate. BLAST mode lasts for approximately 30 seconds before the game continues as normal. During BLAST mode in Multiplayer mode the opponent can't attack with crate weapons and the wooden barrier doesn't open, but they can send the bazooka over the barrier.

BLAST mode was not included on the Game Boy Advance version of the game.
