Unique action game Deadly Creatures was recently pushed till later this year, THQ explains why.
The publisher spoke of why the game needs more time in the studio. Simply, it needs to be polished and the framerate improved enough to gain a solid and smooth experience on Wii. Since gaining a mixed reception at E3, the combat system and camera work have been seen improvements, as well an issue with targeting enemies.
Similar games, and a possible continuation in the Deadly Creatures line, are said to be in consideration by THQ given some positive feedback from gamers.
