Riding on the multiplayer-enabled coat-tails of Homerun Battle 3D, Com2Us's latest game is going to have the same instant multiplayer matching and worldwide ranking. Sniper Vs Sniper in its single player form has you scouting for enemies with binoculars, then switching to your sniper rifle and aiming with the accelerometer to take them out. (The binoculars give you a much wider view than the sniper scope.)
I wasn't able to try multiplayer, because I was playing one of the only copies of the game in the wild, so there obviously wasn't anyone to be matched up with. But, I got some in-depth descriptions of what to expect of the online component of the game.
There are two multiplayer modes, the first is "Alliance Attack" where players play together shooting enemies from a nearby building. At the end of the match, scores are added and whoever has the most kills wins. The second game style, which seemed much more interesting was the "1v1 Match". In this game mode, each player starts at a random location on opposite facing buildings. They must scan the opposing building with their binoculars to find their opponent and shoot them before they get shot.
