The single player mode has me a bit puzzled at first, as I have COD1 and Big Red One played something and I alone the lack of "health packs" missed initially. If you hurt, so you have to wait a bit and health is back to 100% (in multiplayer). The story in the single player is a little confusing, since one among several application areas (and times) is thrown back and forth. The graphics are impressive, the weapons are not sooo varied, the campaign itself could be designed a bit more varied and nerves in part by repeatedly executed actions.
Short spoiler at the end:
The end is not waiting with a classic "boss", but went for my taste a bit too unspectacular. As the cinematic presentation Lies expect also the end more or less remains open and is indicative of the next part. One tip: the long guy should have a look to the end ...
All in all, a too short and monotonous fun, even for a casual gamer like me. The graph makes up for a lot.
Multiplayer:
Brilliant. The graphics are great, the previously played cards of me (relatively) varied. Long-term fun comes to the allocation of points: the launch / Assist there are points you climb in rank, gets new weapons / extras and must be within the multiplayer modes Mastering challenges. Highly addictive!
Conclusion: The single player mode is quite nice, especially scores with the graphics. Multiplayer mode gives the game a certain something, and ensures long-term fun.
