Arc of Templar
Goody Gameworks blends action and defense in Arc of Templar, a game about purging evil from a castle by filling demons full of lead, and dropping the odd chandelier on them. To play, use the mouse to aim (you'll fire automatically), and [WASD] or the [arrow] keys to move around behind the barricade, keeping the demons at bay. You can activate special skills with the number keys when they've cooled down, and stepping on triggers behind the wall can activate traps when available. Slain enemies drop experience points, and when you level up, you can choose to enhance your Templar's abilities, or gain a new power altogether. You'll also gain heroes who will fight automatically to keep enemies at bay... don't worry if they get knocked down, they get back up again! (Sorry kids, that's as current a reference musically as you're going to get out of ol' Auntie Dora.) Just watch out, since if they get close enough, enemies can target you, too, and if you get taken out, you'll have to try the level again.
Like all of Goody Gameworks' titles, Arc of Templar is cute as the proverbial button. The sprites and pixel artwork look great and have a ton of character, while the gameplay manages to be simple and fun. This isn't the first time they've tried a spin on the defense shooter genre, but the downside is it's hampered by some shoddy AI, which makes your computer controlled teammates inefficient meat shields at best, especially with the lack of a really precise positioning system as opposed to the slider. It gets grindy just a wee bit too soon, which may put off players who want to get by on skill, rather than how many levels they've been able to sink into skills. If you don't mind a bit of an uphill climb, or even prefer a game that makes you dig your heels in, however, Arc of Templar is a solid and unrelenting little defensive shooter that you can roll up your sleeves for.
