The other "We got hacked" freebie.
The game puts you in the shoes of Templar, a guy fighting for the... good guys against the Helghast, a group of guys with luminous red eyes. And it's your mission to... bring them down? Yes, there is a story to the game, and it is told via text before each mission, and on cut-scenes every now and then. What's the problem? The text summaries take to long to pan out, I was willing to give the story a chance, but these "scenes" took too long to go from page to page, so I just gave up on it. It's not an interesting story, to a newcomer, anyways.
Every now and then the game will give you a CPU ally, they are pretty self sufficient, and you can order them around with the directional D-Pad. Besides shooting bad guys, placing C4 or disabling mines, you'll also come across cases. These cases are worth "money", which further unlock weapons for you to start each level with or unlock upgraded versions. Speaking of weapons, Templar can only carry one weapon at a time, if you run out of ammo, you are outta luck. Levels have plenty of "stashes" placed throughout, where you can get more ammo, different weapons, health packs or grenades, so it's hard to run out of weapons. Lastly, clearing each chapter unlocks a small collection of Challenge levels, they come in a small variety of placing C4 in certain places, shooting targets or even surviving an endless slew of enemies for as long as you can, the latter being easily the most fun of the lot, while the others are passable. Scoring on these challenges unlocks "perks" for you to equip before each mission, these are small buff like carrying 3 or 5 grenades instead of two, or placing C4 faster, earning Gold on all challenges gives you infinite ammo! Each of the 16 missions lasts 10-30 minutes, but the challenges and finding all collectibles do offer a decent replay value.
Finally, the game does offer local Co-Op and Multiplayer... which I couldn't try since I don't know anyone else that has this game. It does seem like it could be interesting, though. Then there's also a downloadable fifth chapter, but since it's not on PSN and Killzone.com went down, you have to download it elsewhere and get it to you PSP via USB cable, which I don't own yet, so I couldn't try it either.
Killzone: Liberation is a game I didn't enjoy. According to the Internet, it's a good game, so I might be on the minority here, but I just couldn't get over how slow-paced it is, and how awkward the controls were.
4.5 out of 10.
