Bought Crackdown for Halo 3 beta, discovered it was AMAZING, better than Halo 3. Everything about it is absolutely wonderful. I know I hail a lot of games for being awesome, but goddamn, Crackdown is just so unbelievably fun.
Crackdown 2 is also amazing and wonderful, but there weren't enough big battles. I liked the setting but it wasn't as cool as the first. I do like the whole freak/zombie thing, and the boss things were pretty neat, but there wasn't enough focus on cell. Most of what they did was just piss you off when you're trying to do stuff. Also, back on the big battle thing; I mean I know you're basically the police, but I loved having hitsquads trying to run me down, which would result in large-scale gunfights in the streets. The freaks aren't fun to fight unless you're in the cell battle bus or whatever, or running them down.
Co-op is amazing, especially since the upped the players to 4 and added helicopters. Me and my teammates airdropped players and vehicles into battle areas, it was so awesome. I don't know what visage was talking about, I've never encountered that issue online. In-fact, the player I played with leveled up and joined games specifically so they could help other people out, and proceeded to help me finish off some breaches and get achievements. Contrary to Visage, I do not regret buying it. It is one of the few games that can remain fun even after you beat it like 5 times.
I was incredibly disappointed by the Crackdown 2 demo. It feels exactly the same as the first one with all of the same problems. Not buying it until the price drops substantially.
What problems?
Ultra Violet rays electrocute you? Wat.
The UV shotgun fires a ball of plasma that kills freaks, but basically throws/tazes people.
Also I just found this out recently: You can attach things to other things using the mag. We were able to airlift vehicles by using the mag, and even put a bug on top of agency tower.
