OK, misnomer -- I just picked this up at Gamestop (it's just hitting shelves today, afik) and can't play until tonight. So my only impressions are the box is plastic, and the manual is made of paper.
However, if you have any questions about it (controls, multiplayer modes etc.), I'm happy to peek at the manual and share some factoids at least. Although some are saying it's "just like Killzone: Liberation," the graphics and character models seem larger, the isometric view seems a bit different angle than Killzone's, and it certainly still seems like it'll play more like it's SWAT brethren (I'm a big Killzone: Liberation fan, it was the PSP "system seller" for me, but I'm all for variety ).
Few bits I got from the manual (I'm sure previews mentioned some of this, sorry if I repeat anything):
-You directly control one SWATee, with 2 squadmates (vs. 1 plus 4 squadmates in the PC games). You have a pool of 4 squadmates to choose from. Each has 5 skills they can develop over usage/time: Accuracy; Intimidation; Interrogation; Observation; Leadership. Each has a "Default Effect" and then 4 levels of advancement.
For example, Leadership's default is simply the ability to control officers. But get it to level 4 and you can revive each officer once with full health. Intimidation's default effect is "10% more people will surrender." At level 4 as many people as possible will surrender, and the officer can kick down doors with the force of C2. Sounds pretty cool - the skills are detailed on the back of the manual, btw.
-Square button issues default team orders; the R button brings up a control cursor and then you can see a full options menu including the typical SWAT game stuff (mirror under door, kick in door, blow open with C2, stack the team, or open the door and toss flashbang or gas grenade. When interacting with people options are restrain or interrogate. Sounds good, I'll hafta see whether this feels smooth or clumsy on psp.
-It's no Gears of War, but it says you can position an officer behind objects and they'll automatically assume a covered position. You can peek using the thumbstick and then fire from cover.
-A few buttons see double duty. For example, the Up directional arrow button is: tap to change weapon firing mode; press and hold to reload.
Multiplayer modes [Alas, it's strictly 4-player Ad-Hoc Wi-Fi -- there's no infrastructure [Internet play] support at all; I'm more interested in the single player, but I'm sure it's disappointing to many PSP fans]:
-Football: 2 or more players compete to collect hostages and bring them back to their base.
-Rodeo Round-up: 2 or more players lead assaults on their own personal load of a map selected by the host.
-The Great Escape: One player chosen to play as a SWAT officer whose goal is to escort a hostage from one point on a map to another. The other player(s) control terrorists whose goal is to stop the escape. Twist: The SWAT officer is escorting the terrorists' leader so there's a penalty if the terrorists get sloppy.
-There is, alas, no co-op, which is kind of a shame (I was a big SWAT 3/4 co-op fan).
