Cap'n Magneto

The game takes place on a top-down 2-D map, which is colorized in recent versions. The characters, including Magneto, appear in side view. By modern standards the map is quite small, wrapping around after about three window-sizes, the windows remaining limited to the original 512 × 384 resolution of the early Macs. Magneto could move only in the four cardinal directions, either by pressing buttons on the "control panel" on the right side of the screen, or by using the cursor keys in modern versions (early Macs did not include cursor keys). There are several other buttons used to identify objects and translate the alien speech, pick up or drop objects, and to use the various equipment found while playing.

Cap'n Magneto is based on finding and collecting important items scattered around the map, and then using them to access different areas of the map and continue in this fashion. Most of the map consists of various "buildings", including the broken remains of Magneto's ship, as well as a useful apple tree and a small island. Some of the map locations lead to "new maps" when entered, areas that are represented by smaller buildings on the original "outdoors" map.

Also scattered around the map are various alien characters who are sometimes friendly; friendly aliens will follow Magneto around the map, periodically saying various "help text"-like statements that are spoken using the Mac's speech system. These statements come out as an odd garbled sound and text until Magneto retrieves his tricorder from the ship's wreckage, although it is possible to partially decode the text labels as the symbol font used to obscure the text is similar enough to make some text legible.

Friendly aliens will help Magneto in combat, dramatically improving his odds of winning the game. Although friendlies are not particularly strong attacking, enemies attacking Magneto have an equal chance of attacking any friendlies nearby, reducing the number of hits Magneto will take. Combat is very simple; the player clicks on a target and holds the mouse (or cursor key) while a "battle counter" appears and displays random numbers, the idea being to release the mouse when the number is high in order to do more damage. Magneto's health is displayed as a small bar at the bottom of the screen, and will regain strength with time.

Scene early in the game as Magneto searches the wreckage of his spacecraft. He is being followed by a friendly alien (smiling, with his hand out) while two neutral aliens hover nearby. The "Identify" button has been pressed, labeling the various objects, but without his tricorder most of these are translated to gibberish by rendering in a symbol font. The tricorder is visible at the bottom of the screen, not having been picked up yet. The green bar in the title area at the bottom is Magneto's health, currently full.

The game was originally written by Al Evans for the original 128K Macintosh in Lisa Pascal, and was released as shareware in 1985. It is a rewritten and expanded version of Evans' 1983 Apple III game Cap'n Magneto.[1] Evans describes it as "the first truly interactive game for the Apple Macintosh"[2] and writer Richard Moss claims it is the "first free-roaming direct control adventure game" released for Macintosh.[1] This version continued to work on all of the early versions of the classic Mac OS and was a common shareware fixture. The game stopped working under System 7, and several compatibility updates followed.

Macworld named the Macintosh version of Cap'n Magneto the "Best of Show" as part of its Shareware and Public Domain Game Awards in 1987. Macworld praises Cap'n Magneto's gameplay, stating that "Although Cap'n Magneto resembles other games with its emphasis on fighting and destroying enemies, it requires strategy to win. Moreover, making friends is at least as important as fighting, which sets Cap'n Magneto apart from the rest. Cap'n Magneto successfully combines arcadelike features with the puzzle-solving spirit of a good adventure game."[3]

In 1990, MacUser magazine named Cap'n Magneto one of the 200 best Macintosh products.

In 1993, Cap'n Magneto was updated for compatibility with System 7 and Macintoshes up to the Quadra 850. This version was never widely distributed, as the original publisher went out of business before it was released. A quickly-patched version running on Mac OS X appeared as one of the "hacks" at MacHack 2000, known as The Return of Cap'n Magneto. In 2005 a new Carbonized version was released to run natively on Mac OS X, and the original and 1993 versions were released free for download. The Carbonized version is not compatible with Intel-based Macs running Mac OS X Lion and newer versions of macOS, due to the dropping of Rosetta support. In 2020, Al Evans released Cap'n Magneto as freeware and posted a free-to-use registration code on the official Cap'n Magneto website, following the demise of KAGI, the company that handled the game's registration.
