Death Pays Off in Dark Void with XBOX 360 Achivements
Many achievements can be gained by taking advantage of Dark Void's action-packed battles and killing a certain number of enemies in a certain way, talk about incentive to kill. Specific kills achievements is similarly obtained in Army of Two.
Blue Light Special - 15pts - kill three enemies with one grenade, not too difficult, I actually got this one on accident trying to survive an ambush.
Rocket Clothesline - 15pts - melee an enemy immediately after landing. Be sure to start your descent with full life as you'll likely have to absorb some intense firing unless you're able to get a jump from above.
Killing Spree - 20pts - kill 10 enemies within 60 seconds, I got this one very early on in the game after your first encounter with a turret, after you kill the watcher using it, wield it yourself as more watchers break through a door across a bridge.
Big Bang - 30pts - destroy a knight with a grenade, this is all about timing. Fortunately, you'll know when the knights close to being destroyed.
Float Like a Butterfly - 20pts - escape from 10 melee attacks, when in close combat watchers may grab you prompting a button sequence on screen, complete the sequence and you should escape.
Those Aren't Fortune Cookies - 15pts - step on 10 slugs, there aren't too many levels which feature the slugs, at least not until the second episode. Stepping on slugs is the same as executing a melee attack on a normal bipedal enemy.
Cleanup on Aisle Three - 15pts - kill 100 enemies with headshots. Unless you're obscenely accurate, this may take some replay to accomplish. Use the watcher's sniper for optimum accuracy.
The Squishy Center - 20pts - kill a sarpa piloting an Archon. Once you disable the four legs, do the 'B' button prompt, but enter at front. This way, you run up the back to the cockpit and follow another button sequence to kill the sarpa. The last chapter of the first episode is a good place to do this.
Cliffhanger Killer - 15pts - kill 50 enemies while in vertical cover, you will definitely get this by the time you finish the campaign. Certain ledges let you press 'X' to get into vertical cover to shoot at watchers below or above you.
99 Red Balloons - 15pts - kill 10 enemies while they're in an anti-gravity bubble. There's a weapon that shoots these bubbles, equip it an another weapon, make em' go up, switch guns and take em' down.
Blind Luck - 15pts - kill each type of foot soldier using blind shooting, there aren't many varieties of foot soldiers so you should get this while completing the game.
Light Up the Sky - 30pts - destroy 25 targets with the Ark's AA guns, you can get a bunch of these during the chapter, "Defending the Ark."
Fireworks - 15pts - kill 10 airborne enemies with grenades, this is much tougher than "Big Bang." Again, all about the timing.
Rochambeau, I Go First - 15pts - kill 50 enemies with melee attacks. Pretty self-explanatory.
Master of Arms - 15pts - kill an enemy with every rifle weapon. There aren't all that many different weapons to choose from, this may be done through the natural course of completing the campaign.
