AIM Productions released Gyroid

AIM Productions has produced several quality titles (you may want to check out section 2.3 here for a quick listing/evaluation of most of them). Their latest release, Gyroid, is a quite decent space shooter available here and costing $14.99/€14.99. There isn’t much to be said about the game: you’ll find out what it is about in a few seconds. I, therefore, only concentrate on the stuff that potential buyers would like to know: How it compares to other, similar titles? Does it offer anything superior to them? There’re few pseudo-3D titles similar to this game. The one that exist are the following: The aging, “oldie but goldie” (and fully WM5-compliant - just tested it on my x51v) Interstellar Flames by Xen Games is about of the same quality/playability. The also pretty aged Metalion2 by ZIO Interactive (download here), which is also WM5-compliant (but not with the WM5 hx4700, where it complains about “data file not found”) has the advantage of being able to be controlled by the stylus (which is painfully missing from the AIM title). It, however, has a much more boring in-game music, much fewer powerups and, visually, isn’t as nice as Gyroid (it's even more pixelizated). The now-free Solterra by Blacksmith Studios (see review here) is a bit more boring than this title, but it supports the Intel 2700G 3D chip in the Dell Axim x50v/x51v and, therefore, may be a better choice (and, again, it’s free) for anyone having the hardware-accelerated Dell PDA’s. Pros

1. broad platform compliance from Pocket PC 2002 to WM5 (runs flawlessly even on my iPAQ 3660 - except, of course, for the multiple buttonpress problem)
2. you can’t go wrong with classical in-game music :)
3. a lot of power-ups as opposed to Metalion 2 and Solterra

Cons

1. (- as with so many other games, incompatible with WM5-upgraded HP iPAQ hx4700)
2. no autofire and/or no touchscreen control support to ease the life of Pocket PC owners with hardware buttons not supporting multiple button presses (for example, iPAQ 36xx/37xx owners) or devices that have double-press support on by default (for example, the Pocket Loox 718/720 – see this article for more info.)
3. no Intel 2700G support (unlike with Solterra)
4. while it’s working great on VGA devices, it’s quite pixelizated

Verdict While definitely not an Anthelion II (probably the best pseudo-3D space shooter) killer, Gyroid isn’t a bad game. You may want to give the trial a try. UPDATE (03/23/2007): Allen Gall's review
