overall, a great game.
the online is very intese with up to 40 people. theres stat tracking for ranked and unranked games (separate) as well as a friends and clan system. there is virtually no lag, even with 40 people in a server.
the graphics are good, but not the greatest. some of the levels look quite amazing with far draw distances, hectic battles, and not once did i notice any slow downs. all in all, resistance is a great looking first gen game.
there are many weapons and grenades in resistance, and you will find them as you play along through the campaign. each has a secondary trigger and some are very fun to play with. and as i said before, once you beat the campaign, you will unlock other weapons.
overall, resistance is a great game, definitely one of the best launch titles to date.
