1. Start with a class with OMA, switch to another class, your kills still count towards getting OMA Pro.

2. Start with any class, use equipments and bullets. Use OMA to switch to same class as a refill. This will give you the opportunity to use 'infinite' nube-tubes (not patched yet, but they threatened to do so).

3. Have an OMA class with C4 and an OMA class with Claymore. Drop a claymore where wanted, OMA to C4 class, drop C4 in front of Claymore to make a huge blast radius for your Claymore. OMA to claymore class again, drop another Claymore, OMA to C4 class and drop another C4 by the new claymore. OMA to whatever class you want without Claymores/C4 and use that equipment while your back is covered by 2 extra-powerful Claymore spots.

4. Shoot from equipment-listed as a seperate cheat on this site.
