Gameplay is similar to the Strike series, you fly your helicopter from a third person perspective and have to destroy enemy installations and units, as well as using your crane to pick up power ups and ammo.
Getting SWIV up and running under Windows 95 may prove to be as difficult as playing the game. The plain-vanilla test machine encountered Windows crashes out the wazoo before the game would even launch, and unless you have a 3Dfx card, you might want to consider installing the straight DOS version instead. You won't miss much, as 3D acceleration does very little for this game - aside from smoother-looking terrain, there's little worth mentioning.
Bugs aside, SWIV is a fun but shallow shooter. Keep in mind that you'll need the reflexes of a six-year old Nintendo junkie to stand a chance - but if you think you've got what it takes, this is a solid blast-fest that shooter fans should consider picking up.Gamespot: http://www.gamespot.com/reviews/swiv-3d-assault-review/1900-2533328/
The game ran in 320x400, an uncommon resolution that was supposed to be stretched to 4:3 (making the pixels double wide). This graphics mode caused several issues in Windows 95, making Gamespot recommend users to play the DOS version of the game in their review, despite it missing support for 3dfx hardware acceleration. Gamespot scored the game a 5.5/10.
