I'd say out of the 4 maps...
1 is amazing (Containment)
2 are great (Turf and Sanctuary)
1 is good (Warlock)
No actually bad maps (i.e. something like Waterworks, that level is uncool). Definetely worth the $6.99 CDN I (my parents rather, :lol: ) paid for them. I'd recommend buying them a.s.a.p. If you only get the 2 free ones, your Halo buds will call you a cheap bastard. :twisted:
