Just like the levels in Gears of War, the entire game is scattered with objects the game’s protagonist, Logan Keller can take cover behind at the simple touch of a button. Oh! and in case you’re pinned down by heavy enemy fire, you could always indulge in some blind fire to save your life (it’s not very accurate but it’s still a life saver at times). Gone are the days when a single bullet could end the entire mission; in Vegas you can absorb a fair amount of damage before you actually die. Since there is no health bar in the game, as and when you get hit, the screen begins to blur and you start breathing really heavy which means it’s time to take cover, regenerate your health and head back into the action. With this new system a lot of the tense atmosphere synonymous with most Rainbow Six games has been lost to a certain extent and there will be times when you’ll be tempted to go all out, guns blazing et al, but then again, a quick bullet to the brain reminds you that this is a Rainbow Six game at the end of the day and you will have to tread carefully.
Another cool addition to the series is the fact that you and your team can now rappel down buildings and breach rooms in a highly cinematic (and not to mention cool) way. If for some reason you feel the room’s far too dangerous to breach, you can even invert you character (by pressing the crouch key) and take out the visible enemies, before entering that room. Not keen on making a grand entrance? No worries, clear the room out using your teammates and then flank the enemy while they’re distracted. Speaking of your teammates, they are pretty sensible this time round and won’t just run out into the open to get shot; they’ll take cover, value their life and most importantly, provide the cover and back up they’re actually meant for. As and when once of them gets injured badly, you can bring them back from the brink of death with a quick shot of some sort of magic portion, but unfortunately, they cannot reciprocate the favor for you.
LOL his hands are like an animals!
