"Active Lancer is a 2D shoot 'em up video game created by Freeverse for Mac OS 9 and Mac OS X."
The 3rd download is the official dmg image from Freeverse containing the updater.
"It plays in the style of many old school computer games and features little plot line or story development. The demo is downloadable from macgamefiles.com however it is no longer included on freeverse.com. There are several levels the player is required to complete. It lacks a multiplayer mode but two players can play together on the same computer. It was much less successful than Freeverse's popular WingNuts Series.
It was re-released as part of a 'Best of Original Mac Games' bundle from Freeverse."
"In the game the player is cast as a member of the 'Active Lancer Corps'. He is the lone survivor of a failed attack on the home world of an alien race known as the 'cherries' where he has to face fast unending attacks by the aliens." --Wikipedia.orgCompatibility
