Though the Tony Hawk series has been appearing on the PC since Tony Hawk's Pro Skater 2 was released in 2000, the popular console series hasn't found the PC audience quite as accepting, even after last year's Tony Hawk's Pro Skater 3 was released with additional online multiplayer capabilities that weren't found on the PlayStation 2. Perhaps this lack of acceptance has a lot to do with why Activision isn't handling the publishing duties on Pro Skater 4. Instead, the publishing has been left to Aspyr Media, a company better known for its Mac versions of popular PC games. It appears that the smaller publisher doesn't have quite as wide a distribution chain as Activision does, making this latest installment in the series a little more difficult to find than you'd expect with such a well-known series of games. The PC port may be on par with previous PC installments, adding higher resolution options while maintaining the gameplay that made the series great, but the narrow distribution and somewhat clunky external player-matching program make for a great game that's difficult to play online.

Tony Hawk 4 is another excellent installment in Activision's flagship series.

Tony Hawk 4 does away with the two-minute time limit so commonly associated with the genre. While this takes away the exciting challenge of trying to accomplish all of a level's objectives in one run, the game's larger levels would make such an effort impossible anyway. Instead, goals in Tony Hawk 4 are spread throughout the level in the form of various bystanders with big arrows floating above their heads. Skating up to them and hitting the grab-trick button will make them talk and will start the goal, which in turn starts a timer. Many of the goals are the same sort that the series has featured all along. You'll still have to reach certain score plateaus by pulling off long strings of tricks, you'll still have to collect or break various goal-specific items, and you'll still collect the letters that spell "skate." New types of objectives include some combo-based goals that ask you to beat a specific score with one combo. You'll also have to collect letters that spell the word "combo"--without landing your combo until the word is complete. The size of each area lets the game pack a lot more goals into each of the game's nine levels, and some goals are only available once other objectives have been competed. Completing a goal also earns you upgrades for your skater, such as cash, new slots for special tricks, or stat points.

All this goal completing leads up to unlocking the pro challenges, which become available when you've completed 90 of the game's 190 total goals. Goals can be completed with any of the game's skaters, so you won't have to play through the game multiple times to see all there is to see. But the pro challenges ensure that you'll still play the game with every skater. These challenges are larger in scope than your average goal, and many of them attempt to tie into a skater's actual career. For example, Tony Hawk's pro challenge has you gapping from one rooftop ramp to another, doing specific tricks as you go. Bam Margera's pro challenge takes after his popular CKY series of videos, putting the Jackass star in a shopping cart and challenging you to race, hurdle, and slalom your way from the top of Alcatraz down to the bottom. Bob Burnquist, who is one of the two Tony Hawk 4 pro skaters not featured in last year's game, has a pro challenge that is styled after his event-winning performance at the Op King of Skate competition, which aired on pay per view last year. In that competition, Bob opened up the top section of a full loop and rode all the way around it. In the game, you'll take this one step further, doing specific tricks while gapping the ever-widening break in the loop. The pro challenges are unique, more difficult than your average goal, and quite a lot of fun. Completing a pro challenge unlocks that skater's ending video and also opens up a new collection of more-difficult goals in every level.

A newly redone career mode and additional online options are some of the highlights.

Many of the level goals in Tony Hawk 4 will be pretty difficult even for series veterans, so accomplishing them will be really satisfying. The game throws some strict time limits at you in some of the goals, and some of the later combo goals are tough to pull off. In previous games, failing a goal or missing a jump meant that you had to spend time skating around to get back in position. Here, when you fail a goal, you can use the pause menu to jump right back to the start of that goal, instantly. This gives the game a real trial-and-error feel, letting you reattempt the same combo line over and over again until you finally get it, though being able to restart a goal at any point keeps this from getting as frustrating as trial-and-error-style gameplay usually gets. You can also jump to any goal that you previously tried, which is a handy way to skip around from place to place in a level.
