Players do not get infinite lives in multiplayer, every death counts as it counts against the amount of times they have to gain an advantage.
However, speaking in terms of the combat itself, the multiplayer does a fantastic job demonstrating what a realistic shooter truly should be and how teamwork is a necessity. For example, in push, players have a certain number of chances to receive revival or else they will have failed the mission and this is the same for the enemy team as well. Most of these have been done before, but in many ways, Insurgency adds its own spin to them. The game modes consist of firefight, hunt, push, and skirmish. The game contains 8 different maps, 4 game modes, over 14 weapons, and that's not including customizations, nor the chance to create your own maps as well. Primarily, the game itself features a good chunk of content.
But Insurgency focuses on making a realistic shooter rather than a top of the notch graphically enticing title which is definitely a plus in my book. But it still doesn't demonstrate factors that can compete with other shooters. Look deeper, however, and the game is far more than just a mediocre shooting experience. At first sight, Insurgency demonstrates nothing more than the average Battlefield or Call of Duty experience.
