The Site 4/Area 51 is a light gun arcade game. The Site 4 is an upgraded version of Area 51 with improved graphics. The Site 4 lets you enjoy few training games prior to the original game as a warm up session.
At max, two players can enjoy this game. Though it is a light gun game yet it has some features that make Site 4 stand out of the league of traditional light gun shooting game. One of it is that no reloading of the gun is required, so you never run out of ammunitions. The player needs to shoot out the bad characters and miss the good characters.
The game is short and crisp with only four levels as a part of it.
