I remember a map I played(I don't have it anymore) that was fun, and was a survival map.
It had a -save/-load system(then again, which survival maps doesn't these days).
Anyway, the -save/-load is based on "Rank experience". The higher your rank, the more exp you gain. You always start at level 1, but the higher the rank, the more exp you get I think.
Anyway, it had marines(yes, I know most maps have marines too).
One thing I remember is that you spawned in an area with water, in the bottom right of the map.
It has the weapon/ammo system, like those Zombie Survival maps have.
It had a weapon that shot multiple rockets in an area.
One of the enemies I remember are gargoyles and a bunch of other stuff.
Yes, I know, really vague description(considering a lot of maps actually fit it) but in case anyone knows what I am talking about.
You spawn in the bottom right, in some area with water, all players start with the "stim pack"(blood lust) ability, and there was some rocket firing weapon.
Anyone know what map I am talking about?
