since i've got the 3 bonus maps (pre-order maps) i will make a somewhat review of them.
Rail-Yard: it would have been better if the enemies were Infectees instead of the J'avos, since this level is from Leon's campain.....anyway, this level is "tight" (layout-wise), it seems that this level is made, that you should play it in a dark room, i say this because when i played it in a dark room; i was able to see the level clear but when i played it in a decent lit, i had a hard time able to navigate through the level. (but hey, it's my prefrence to play the game in a dark room
)
High Seas Fortress (aka the "Neo-Umbrella" ship but in a sun-set time of day): not much to say about this, but this level is wide open.... i am in a boarder-line state of liking this level.
Catacombs: like the level above this, i've got nothing much to say. i have a good liking enough for this level.....
