Resistance 2 is a fun addicting game, but it definitely requires some fixing.
The campaign begins where it left off in the first game, though there are many changes : Maps are more colorful and differently designed, new weapons are introduced, the weapons from the first game have a different feel, new enemies and bosses, etc etc.
As you progress through the game you'll find bosses, but I found these bosses lacking depth, since all you have to do is shoot the F out of them with whatever weapon the game gives you. It also seems like you go through more variated locations than the first game, which I found a great improvement.
Anyway the campaign is around 7-10 hours long, I enjoyed playing through it and it had it's moments. Don't be expecting a great ending though because it's..... a cliffhanger! With a plot twist I guess. When you finish the campaign mode you might want to play it again for trophies or intels, but I suppose that also depends on how much you'll the campaign.
Continueing to online mode..
I gotta say the online mode is very fun and will keep you occupied for a long time. You can either play co operative or competitive. Let's start with the basic things.
In competitive you get to choose to be either human or chimera. You gain new faces/armor/accessories/clothes as you level up. Although they are just for decoration, I still found this a nice feauture.
In co op, your gear actually boosts stats. For example : if you're a medic, a certain item will increase the range of your healing shot. Although in this mode you have to buy equipment with the "Grey Tech" you get in the co op missions.
There are also berserks available, and it's your choice which to equip. Every berserk gives something unique and different. For example : there's a perk that will constantly heal you in an area when activated, or will greatly increase your defense for a short amount of time etc etc. when you get enough exp from shooting people it can be activated.
Now competitive doesn't have many modes, but you'll still be coming back for more, and you can always party with your friends to make it more exciting. It has Death Match, Team Death Match, Skirmish, and Core Control (which is basically capture the flag). Every mode feels just fine and is easy and fun to play, there are a few complaints though :
1. You spawn on a completely random places, you might spawn with your back facing the enemy or you may even find yourself spawning on a grenade.
2. Although there are many maps and a fair amount of variations, they lack interaction and just feel sort of blank.
3. Sometimes when there's incoming fire in front of you, you don't see incoming bullets at all and don't notice the fire is coming in front of you until you're dead (this doesn't happen that often though).
4. Some players don't immediately die when they're supposed to, they just keep walking and suddenly die a few seconds later even if you stopped firing.
5. Weapons are very unbalanced, some are close to being completely useless and get left out. So almost everyone uses the same 2 guns.
Anyway on to co op. There are 3 classes in co op : Soldiers, who are basically just there for offense, Medics, whose main purpose is to heal allies and have crap offense and Special OPs who have long range weapons and refill ammo. I have no real complaints about the co op mode. It's entertaining and works out fine as long as you have balanced teams.
In the end Resistance 2 is a great game with some complaints, but if you can forgive it for it's flaws you'll spend a lot of time with this game. Just don't expect a very depthy shooter. I suggest anyone that likes FPS games, to at least give it a try.
