SWIV

SWIV is a vertical scrolling shooter and an unofficial successor to Sales Curve's conversion of the side-scroller Tecmo arcade game Silkworm. One player controls a helicopter and the other a jeep, with the jeep transforming into a boat when the vehicles drive over water. As well as plenty of blaster fodder, the game also features a mid-level enemy inspired by the "goose" from the earlier title Silkworm. Parts of this enemy would fly onto the screen and assemble into a vehicle before starting to shoot at the player's vehicles. If the "goose" is destroyed, it drops power-ups.
