The Missmurder case, Mercs wear yellow, with red polkadots, all melee weapons are a high tech circular saw named the pizza cutter.
The Alpha Strike case, a possible reappearance of old alpha design for mercs, the younger looking Sawbones and glasses/beanie wearing Fragger to appear once again, with all mercs wearing the light grey and black/blue armor shown in earlier designs.
Seasonal Crates, mainly dropped during seasonal events, Flame patterns, skulls, cobwebs, subtle vampire bats here and there for holloween, with a possible Michael Myers like halloween knife. a knife made to resemble a flat metal candy cane for christmas, not too exageratedly cartoony, but just a bit of a sense of humor to use something related to the season thats at hand.
The Red Alert Case, Head to toe in Crimson red clothing for the merc, with possible white designs rather than a camo pattern.
The Nerf Case, To remind people it is all just a game, by making the guns and clothing bright blue and yellow instead of the scary camo pattern and tactical guns.
