mp_gisa2 (I made wt if u too nab to fin xd)
Note that some of these maps are designed for 125fps so I'd recommend playing them with that to get the proper nostalgic experience!
Any more 125-only maps anyone could suggest?
Doesn't matter if they're popular or not, just that they can be finished 125 only, cheers
edit: mp_beast seems to be the best I've found for 125 (thanks ricin)
