What I particularly remember was learning my dad’s strategy: stay put in the center of the screen, shooting down the asteroids from there, and — if at all possible — avoid moving from that spot. Once you turned on your thrusters, you’d be drifting off toward the edges of the screen, where new asteroids spawned, and it was pretty unlikely that you’d ever be able to stop completely until you died. It became my habit, too. Ever since then, that’s been my own modus operandi in most Asteroids-like games (and probably also explains my tendency to camp out with a sniper rifle in first-person shooters rather than charging into the fray with a melee weapon).

You're still kinda triangular, but the background is much more interesting than before.

Atari has updated their classic space shoot-’em-up for iOS devices: Asteroids Gunner puts you back in the pilot’s seat in a top-down, screen-wrapping arcade game. The premise is still pretty much the same: shoot rocks (and the occasional alien), don’t die. Of course, there’s a lot of other bells and whistles, too: you collect gold-colored crystal shards that are released when you destroy rocks, and you can also get power-ups that give you temporary weapon boosts, shields, and the like.

My stay-put-and-shoot strategy doesn’t work so well anymore, since that doesn’t really let me collect any of the things I need to pick up, so I’ve had to abandon that. Also, the controls are different now: it’s a dual-thumbstick setup, with your left thumb controlling the direction of the ship and your right thumb aiming the gun. In addition, you can have up to two bonus slots above your right thumb that can store weapons, shields, or other bonuses.

The Bomber ship can be unlocked for better firepower.

The game works on the freemium model: the basic app is free to download, and comes with your basic Scout ship and 50 levels in the Alpha zone. As you play and collect crystals, you can spend them to upgrade weapon slots, power up your ship, and buy repairs. However, there are some things that require Space Bucks, which must be purchased in-app. For instance the two beefier ships, the Bomber and the Miner, can only be purchased with Space Bucks. Unlocking the Beta and Gamma zones also requires bucks, and there are very useful Omega Technologies which are much easier to buy with Space Bucks than with crystals.

You can purchase Space Bucks with crystals, but it’s not a great exchange rate, and you’ll be grinding away a long time if you want to go the entirely free route. Still, even the free-to-play part of the game is fun and will provide a good amount of gaming, particularly if you go after all the achievements. Oh, and it’ll cost you $.99 to turn off the ads, which appear from time to time at the bottom of the screen.

Go shopping for nifty upgrades to your ship.

I got a sneak peek at the game before its release, but there were still some bugs that made it crash on my iPad. Since then they’ve updated it and it seems to be working fine now. It’s pretty incredible to look at the difference in graphics between the original game and this one. The controls are fluid, though sometimes it can be a little disorienting when you’re flying — the background moves slightly, but since it’s so far away, it moves much more slowly than the asteroids up close. It can be difficult to tell how fast you’re flying if the screen is mostly free of asteroids, until you suddenly crash into one.

The game definitely is set up so that you’ll want to spend some more money – at least to unlock additional levels, and perhaps a ship. The Bomber ship is probably my favorite, with its better gun and decent speed. The Miner is a massive hulk of a ship, very slow and with a short ranged weapon, but lots of shielding, and it’s not quite as fun to play. The later levels include different types of asteroids to shoot at, too: a fiery rock that flings a few fireballs out when it explodes, and an ice rock that breaks up into a ring of tiny crystals.

Overall, Asteroids Gunner probably won’t blow you away with either its graphics or its gameplay, but it’s a solid space shooter and the nostalgia factor is pretty high. Sure, there are probably other Asteroids clones out there, but this is Atari we’re talking about. After you’re done playing the original version on your Atari Arcade, grab this one and take it for a spin. The universal app works on iPhones or iPads.

Wired: The top-down, rock-smashing classic gameplay with modern controls and graphics. Free!

Tired: Expect to pay for the extras, or spend a lot of time grinding for crystals.

1. Hey, no problem.. 2. Hmm, getting a little crowded here. 3. Yowza!

So, the App o’ the Day is Teragati, brought to you by Mike Tsao of Attachment Computing (and a stay-at-home dad). Mike described it as a mix of “old-school Galaga mixed in with Doodle Jump-style gameplay” and it’s perfect for a little bit of casual gameplay, 60 seconds at a time (if you last that long). If you’ve played Doodle Jump (or one of many similar apps) you’ll be familiar with the concept: tilt the iPhone left and right to steer while the ship zooms relentlessly forward. In this case, however, you aren’t jumping from platform to platform, but dodging asteroids and missiles, and collecting shiny gold power-ups. You can tap the screen for a shield, but if you use it up you’ll have to wait for it to recharge.

The interface is fairly minimal, with no tutorial or help screen: you just start it up and go. Mike explained that he really wanted the game to involve some exploration, so he didn’t spell out how every single thing works. (Version 1.2 did add some little yellow hint text on the main screen, but it’s just a hint.) It took me some trial and error at first to realize which things would kill me and which wouldn’t. Big rocks and incoming missiles = bad, gold things = good. What about these little green rocks? Or those blue spiky things? Or that noxious looking gas cloud? Well, run into one and you’ll find out.

Of course, as with other “keep playing until you die” games, the difficulty ramps up over time, as you can see by the screenshots above. First you get mostly open space with plenty of room to maneuver around the asteroids. But then the asteroids start coming faster and denser, and even start to drift left and right instead of just straight down. And, of course, there are those pesky missiles. There may be more than that, but I haven’t gotten past Level 6 yet so you’ll have to tell me.

The game uses OpenFeint to tie into leaderboards, chat, friends, and achievements (as well as other OpenFeint games). I didn’t link to my Twitter and Facebook accounts with it but I did like being able to compare scores with other players and check on my (lack of) Achievements. There’s also a little unlock icon on the front page—it provides you with a code, and putting in a friend’s code apparently will unlock some bonuses. There are several locks shown on the screen, for several bonuses, but since I have *sniff* no friends I wasn’t able to try that feature out. The graphics are simple and remind me an old Asteroids-type game I had on my PC back in college. The soundtrack is a trance-like electronic loop that’ll help put you in a half-hypnotic state that sucks you into the game for much longer than 60 seconds. (You can turn off the music in your iPhone settings screen.) You will, however, want to keep the sound on, because there are audio cues that you’ll miss otherwise.

Version 1.2 introduces the Electrodes.

I’ll admit—at first I didn’t really get into the game very much, but then after I fiddled around a little more and made a few discoveries about how things worked, it really started to hook me. It doesn’t offer the variety of some other much more complex games, but for a pretty simple concept it can really help you while away some idle time. (For me, I’ve found that sometimes it’s the simple games that I keep coming back to—for example, I was playing Orbital so much that I decided to give it up for Lent.)

Teragati is a mere $.99 from the iTunes store, and is definitely worth checking out if the idea of a tilt-control space scroller appeals to you. If you buy it, let me know. I’m looking for some friends to trade unlock codes with.

Wired: Simple and addictive. OpenFeint lets you show off your achievements with everyone else who’s playing.

Tired: OpenFeint’s pop-up achievement messages can be pretty distracting when you have a missile on your tail. Soundtrack can get pretty repetitive.
