I have two suggestions for FPS Creator Reloaded. I don't ask too advanced features but I think these two should be more than possible.

1) Hitmarkers: a bit obvious I think. Maybe some extra to add: a simple sound added when hitting an enemy. I don't know how to explain it but I think you'll understand me. A good example was COD MW3.

2) Support for survival mode/waves:
[1] Zones
- I was thinking about using zones. For example you create the PLAYERS ZONE. This would represent the zone where the players will be spawned and this is also the zone that the players have to play in and where the enemys would check for the players.
- Second the ENNEMY SPAWNING ZONE: here the ennemies will spawn.
- And as an extra: SUPPLY ZONE. Here the players can gather extra ammo or body armor...

[2] Paths
- Pretty obvious what these would. You need to connect the ENNEMY ZONE with the PLAYER ZONE, the ennemies will then follow these paths to where the players are stationed.

[3] Ennemy spawning
- Next the spawning of ennemies: You define in a data file or something (or the Export Executable dialog maybe?) every single wave. Data like which characters (uzi char, rpg char...), how much and their health/armor.

Just some brainstorming...
I really want to see FPSC Reloaded to be the ultimate program and I really like it already... and this is just the third Beta version
