Chall Desc : All your base are belong to us

We found what is sometimes called a “meme” on Earth which says 
“All your base are belong to us” in an image that is named rather oddly, can you take a look?

Figure out what this is and retrieve the flag.

tU3/k>!{l$TsJ_ap(U.JM(F|6UVs0P0od}Nf[*t;H

Flag format: IGE{XX_XX_XXX_XXX_XXXX_XXXX_XXXX}

P.S. This is the most based challenge btw

This is a challenge where we use cipher identifier of dcode.fr : https://www.dcode.fr/cipher-identifier

Using that, we get to know it is Base 91 cipher :

Decoding the given ciphertext we get the flag.

THE FLAG : IGE{oh_no_you_got_your_base_back}
