There are a
nice selection of achievements, many of which are focused on acquiring new skills and they unlock
at a steady
pace throughout the game, giving achievement whores like myself an incentive to keep
playing.
The game does have a few different modes outside of its Campaign and usual death match modes, and while the real meat of the gameplay exists in its deathmatches,
playing things like Puzzle Mode can offer a
nice change of
pace — giving you scenarios with limited resources or special conditions that you have to meet by using the tools
at your disposal efficiently.
