- If you have a good pair of headphones, use them as it will greatly increase your awareness. ( Sound of decloaking units and people moving )
- Bind Nanovision to a more suitable key, personally I found "N" an inconvenience and have now reloacated it to one of my side mouse buttons. ( As a result I use it alot more often and you really should, it's great. )
- Use your grenades in a hotspot before running in, they're extremely powerful if the enemy is caught out of Maximum Armour.
- Use a weapon which benefits your playstyle, If you prefer a mix of everything then the Scar is currently considered the best. For CQC personally I'd rather a Feline over any other weapon choice. Very long range the Sniper Rifle is naturally the best.
- Make sure your Modules center around your type of gun;
If you're going to be up close and personally, I'd tend to advise Stealth Enhance/Tracker, Mobility Enhance and Nano Transfer ( Quick to stealth, quick movement for escaping/attacking and earning energy back for killing ).
For an Assault Rifle class there's a few options, personally I've found Nano Transfer, Tracker/Blind spot and Retrieval work best. ( With Nano transfer you have the potential to take on a few enemies at a time with Maximum armour on, Tracker for location enemies or Blind spot to avoid detection and earning kill streaks from a distance.
For a Sniper Rifle, personally I'd pick Nano Transfer again.. Blind Spot and Retrieval. ( Cloaking instantly after a kill, Undetectable by Maximum radar and you'll get Kill streaks from a distance. )
Again these are personal preference, pick what suits your style the most!
- Learn your maps and always out flank your enemies when possible, there are plenty of options for different approaches thanks to brilliant map design.
- Don't risk your life for Dog tags, whilst the rewards are beneficial they are not game winners.
- Always switch to your pistol when reloading, it's much quicker and will usually catch your opponents off guard - I recommend the Nova 12 with extended mags, Large clip size and quick firing to polish off weakened enemies.
- Remember to Slide, this seems like a less obvious tip but depending on your weapon loadout it's very effective.. Personally I've used the Feline before and sliding whilst hip firing will often earn you a kill on an enemy who's reactions aren't up to speed.
- Try to avoid super jumps where possible, this uses a large amount of energy which could cause you problems if you're then caught in a firefight.
- Never break stealth by shooting if possible, always activate Maximum armour and then start firing.
- Aim for the Chest since the hit detection at the moment is rather poor resulting in shots not hitting where they should, by aiming for the chest you increase your chances of killing with lower bullet spread.
As more come to mind I'll post them on here, hope any of this helps and sorry if anyone mentioned these before.. didn't read them all
