This is about the status shown on a player's profile. For the gamemode in Critical Ops, see Ranked Games.
Ranks are a cosmetic game mechanic in Critical Strike Portable and Critical Ops. Ranks are a way to indicate a player's status, although this is represented differently between both Critical Strike Portable and Critical Ops;
In Critical Strike Portable, they are determined by the player's kill/death ratio and in Critical Ops, they are determined by how many ranked games a player wins or loses.
These have no real gameplay advantages or disadvantages whatsoever, other than for cosmetic use.
Description
Critical Ops
Ranks are earned through playing ranked games, accessible through the main menu. In order for a player to rank up, they must placement matches, which consist of 9 total rounds won (unlike casual which consists of 13). The opposite can also occur, so if a player happens to lose enough rounds, they will rank down.
Critical Strike Portable
Insignias for ranks.
Ranks label a player's kill/death ratio, and gives a general idea on their skill. The higher the kill count than the death count the lower the rank. Higher ranks are determined by lower numbers, so for example, the highest rank a player can attain is 1, and the lowest (and initial) rank is 64.
In order to rank up, a player must improve his/her kill/death ratio by killing players more often than dying and ranking down would be vice versa.
