Fast-paced, as most Assault maps are, Glacier is possibly the most objective intensive map there is. However, and quite suprisingly, all the objectives are highly enjoyable. As a side note, the Ion Tank is really, really cool.
Critique:
The possibility for one team member to completely outclass and ninja-style complete all the objectives himself make this map sure to create much hilarity. A well-balanced map that should bring about some nifty competition, if Assault picks up.
