Atlus launched a new trailer for Shin Megami Tensei IV: Apocalypse, coming to Nintendo 3DS on September 30 in North America and to be announced for Europe.

The trailer shows how players will take down the demons that inhabit the game. Focusing on letting players know about weaknesses and buffs to take advantage of.

Atlus details the techniques furether:

1. Strike First - Tokyo is crawling with demons, so if you see one (or a hundred) while exploring be sure to strike first. If you land a successful first hit, you'll be allowed to attack first during the battle sequence. While this doesn't sounds super important, preemptive strikes can mean the difference between life and death. Seriously, death is around every turn in this game, so striking first is a must!
2. Exploit Weaknesses - Fighting demons may seem like a daunting task, but it's not too difficult once you get into a rhythm. Attacks come in eight classes -- Physical, Gun, Fire, Ice, Electric, Force, Light, Dark -- and must be used wisely during every encounter. That's because demons have an elemental weakness that can be exploited to deal devastating damage. For example, battling a gaggle of fire class demons? Don't fret! It's nothing that a little Bufu or Raging Blizzard can't handle. Make sure to remember each demon's weakness to maximize damage output!
3. Use Buffs - While attacks are the bread and butter of a demon hunter's arsenal, utilizing buffs can be the difference between a victory screen or making a sad visit to the underworld. Buffs can boost damage/defense, lower enemy damage/defense, prevent negative status effects, heal the team, and more, so make sure to use them!
4. Utilize the Right Partners - Besides demons, you'll be able to enlist the help of various partners such as Asahi, Navarre, Nozomi, Hallelujah, Gaston, Toki, and Isabeau who can turn the tide of battles in a big way. Each partner offers a different type of support, so it would be best to choose one that best accompanies your team build. Need a healing touch? Asahi is your girl. If extra fire power is what you're missing, Nozomi is probably a good choice. If muscle is needed, no one hits harder like Gaston!  Essentially, partners will fill any offensive/defensive gaps that are missing.
5. Don't Panic - Fighting demons takes a lot of strategy, and can be terrifying when they ambush you into a battle. However, the worst thing to do is panic and let the demons tear you apart in a turn or two. Be patient, take a step back, and take a look at all the attack options you have at your disposal before making a move.
