i will give it 2 out of 10:
rooms(2/10): yes i only had 2 rooms on my first map but there is nothing intersting about the 2/3 rooms you have, the area to the pack-a-punch and quick revive is too small and getting to the pack-a-punch on the first room??? that needs to be fix, you could move quick revive into the main area of the first room and have a power door set there
door(1/10): the texture on the door doesnt work so get another one, the door being priced at 2500 points?? why so high? there is only guns on the wall in the next room (not counting the items under the block), the door is all so a little tall, try making it smaller.
the block in the second room is too pricly and your'll be dead before you can open it, instead of a block make a shed there and have its own door, this would add a room to the map
Guns(0/10): all guns are over priced, some guns are flotingoff the wall but that can be fixed the ratio is also wrong (1 gun in the first room and 3 in the next??), you want to keep the ratio at about 2 guns per room, but if its touching a room with 2 in it, its ok to only have 1 gun init, i wouldnt add 3 guns in a room unless its a big room with muilt levels
perks(4/10): only thing realy good about it, the only promble is there are only 2 and they are in wrong porisons, quick revive is too close to pack-a-ounch and its never a good idea to have to perks (or pack-a-punch) in the same room, jugg is the wrong way around but even if it wasnt it would still be in the wall
windows, zombies and dog(3/10): a little oddly shaped, the windows show where the zombies spawn, this is never a good idea as this removes realicm to the game, think smart, where we they camp and try to make it inpossable to camp there, not only will this make the map hard it will have a more of a nightmare sort of feeling
leaks(6/10): leaks is were you can see outside map and not meant to, there are alot of leaks in the map, most can be fixed by moving an object alittle, other then that you did a nice job
textures(1/10): get abetter texture pack, the texture are very boring and need some work, you can get textures at other places, the texture on the door doesnt work so re-place it
other then that happy mapping
