Buzzsaw+ (Foxton Locks Mix)

Falling-block puzzle game. Crates and creatures fall into the play area in random sets of three in an L-shape. The player can rotate and stack the shapes in an on-screen hopper. Complete rows of crates are eliminated. Creatures can only be eliminated by the titular 'Buzzsaws' - circular saw blades which occasionally appear among the L-shaped pieces and which run left, right and down, cutting through any lines of creatures. Ton-Weights and Star-Bombs also appear as rare extras and these eliminate creatures in different ways.

Points are awarded for rows of crates completed and creatures eliminated. Score multipliers apply the more rows or creatures are eliminated in chain-reactions from placing a single piece.

It is the first game ever produced for the ZX Spectrum to use 'Multicolour' in-game sprite graphics that exceed the machine's standard restriction of 2 colours in any one character cell.

A version titled 'Buzzsaw+ (Box Deluxe Mix)' is also supplied on the cassette version from Cronosoft, which has red (not green) blood spatter effects and re-coloured creatures.

The game borrows the basic play mechanics from NAMCO's arcade game 'Cosmo Gang The Puzzle', itself based on a ticket-reward shooting gallery redemption game 'Cosmo Gang'. This was similarly the basis of the home console game 'Pac-Attack'. However, Buzzsaw+ supplies fewer weapons and takes longer to raise the play speed, allowing the player to take a more strategic approach to gameplay and build up impressive chain-reactions for higher scores.
