The good news is that Neon 2 makes an appeal to Mac users, a segment of the casual games audience the first game did not support even though it was created in Flash. The bad news is this version is every bit as addictive as the original, and that is sure to mean lost productivity everywhere.
As before, use the mouse for control; press the mouse button to fire. What has changed in this version is the addition of the [ctrl] key, which will stop your ship in its tracks. Doing so allows you to pivot around to make easy targets of those pesky enemies that come crawling up your tail. Also added is a smart bomb, triggered by pressing the [shift] key when the smart bomb meter is full. Smart bombs blast away all enemies currently on screen.
Whereas the original Neon had waves of enemies that were announced prior to their arrival, Neon 2 simply sends wave after unrelenting wave of enemies upon you. Sure you can press the [P]ause key to give yourself a break, but otherwise the action in this game is non-stop.
Analysis: Featuring a couple of new and more difficult enemies, and controls that allow for more variation in gameplay, Neon 2 succeeds in taking this very enjoyable idea to the next level. Ali has done a fine job at updating an already excellent shooter and making it not only better than the original, but also into a somewhat different experience. Sure it looks similar, and yet it feels different. Neon 2 augments, not supplants, the fun and excitement of the original. Take your pick. This Neon series of games is classic arcade fun.
