I don't know if Escalation has ever been changed since its introduction, but I believe some newer abilities should be added to the variety of weaponry available in this mode, most notably the Chamber Headhunter and Tour de Force.

Tour de Force is the best gun in the game, and I think it would be a fitting weapon to start off games alongside the showstopper. It might be best to remove the slow for this mode, though.

Headhunter could potentially slot in somewhere around the spectre and judge, with both chamber guns having infinite ammo for this game mode.

Aside from the chamber guns, I think that Neon and Jett ults would be fun in Escalation as well. However, despite being ults, I think they might actually be better for the last stage, being as dynamic and fast paced as they are, similar to the existing big knife fight. Jett knives would come with 2 updrafts that refresh when you hit the ground like the raze satchels, and dash every 2 kills, same with neon slide for her ult.

Overall, pretty simple proposal, but I think it would be a pretty refreshing update to the Escalation mode, and it would also be hilarious to see other agents using these abilities.
