Some of the Best shooting mechanics mixed with poor characters and story is the deal in Killzone 3
Killzone 3 has some superb moments such as sneaking stealthily through a gorgeous helghan jungle, jetpacking through snowy foating oil rigs, and taking down one of the biggest bosses seen in a game. However for all these outlandish moments the story never came together to create the impact of the well paced and constructed Killzone 2. Killzone 2 was more grounded and the story much more believable, though still not great. 3 just comes across as a great experience and a roller coaster ride of one beautiful set piece after another. I feel as though the developer missed an opportunity to expand the gameplay and story of the series.
Overall Killzone is definitely still worth playing because as an audio visual first person shooter it can't be matched. If only the pacing and story came together to create something more than just another Hollywood blockbuster. Especially as we are at a time where gaming is controlled by first person shooter clones. Killzone manages to rise above the pack of FPS with stunning graphics and great gunplay.
