Another light gun game! Dead Space is a terrific horror franchise, and DSE is a sweet adition to that, but its so short!
The story is interesting, but you know right away who is going to die, when a NPC is suddenly involved in the plot, not counting the main cast of course. At leased you won't be bothered with bad voice actiong, as the voices are well performed. Maybe they should be when that is where most of the story is told.
The controls aren't hard, but I found that using the alt-fire on the weapons was annoying, because it was hard to keep aiming at the same enemy while twisting the wiimote. The aiming is generally very sensitive, even on low setting. (In game)
Bottom line is that there is one good play through, but nothing more than that.
