S.W.I.V.

S.W.I.V. is a vertical scrolling shooter and an unofficial successor to Sales Curve's implementation of Tecmo's side-scroller arcade game Silkworm. One player controls a helicopter and the other a jeep, with the jeep turning into a boat as the vehicles travel over water. In addition to 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 flew onto the screen and assembled into a vehicle before starting to shoot at the player's vehicles. When the "goose" is destroyed, it drops power-ups.
