Gameloft's Modern Combat 2: Black Pegasus [$6.99] hit the US App Store mere moments ago. I spent most of the day today playing through the single player game, but need to wait for the multiplayer community to pick up a little bit to get a feel for the seemingly extensive online multiplayer before posting our full review. What I can say right now is that if you're willing to disregard the fact that Modern Combat 2 plays like every other modern military-centric first person shooter, you're going to be in for a treat. Much like Modern Warfare 2, Modern Combat 2 hops around between characters and combat scenarios, and while it all feels a little disjointed, it is a lot of fun. Quick time events have been implemented, you often play with AI-controlled team mates, and the Retina Display-friendly graphics look great in action.
As far as online play is concerned, you'll be able to play in 10 player multiplayer games both locally and over the internet. Four multiplayer modes are included: Deathmatch, team deathmatch, defuse the bomb, and capture the flag. As you play online, again much like Modern Warfare 2, you gain experience for nearly every action you do, and then rank up through 72 different ranks each with their own associated rewards and weapon unlocks. The few games I've been able to play have been largely lag free, and a great time.
Stay tuned for our full review which will be up ASAP, but in the meantime, if you're looking for people to play online with or want to check out reader impressions stop by the thread on our forums.
