Alright, I have big-brained up some ideas for some new maps for this game as well as possible conditions for players in the new environments. Also, this will include a new game option that will allow players to have map-specific cosmetics so they can have loadouts prepared for the different maps.
First, if the devs don’t wanna put in new maps they can put weather conditions on the current maps. For example, they can add-in rainy weather and cloud coverage to make the map look darker and greyer. Yes, this will take out the predator’s cloak and it will make it so that the visor cannot pick up warm targets as well due to them being cold from being wet and it will make it harder to hear sound queues. Now the fireteam will have reduced visibility and will be harder to hear. On top of their body temp being lower than normal if they mud up it will not last nearly as long due to the rain washing it off. Now you can counteract all the negatives for the predator by giving them a noise reduction due to the rain. You can also make it so they move fast or take reduced damage on rainy maps. But I think this would make it a challenge for veteran and new players alike on both sides to have to get used to not being able to have their normal perceptions.
You can also balance this out by making the rainy maps night ops missions or later in the day missions. Now if they choose to add night ops maps they can give the fireteam some basic night vision goggles by default, but they will not provide extreme levels of detail and colors.
Another weather condition/map they can add-in is a snow map like something from the start of AVP or you can have it as fireteam is trying to infiltrate an arctic research lab. This will make for a change of scenery as well as add an element of checking your cosmetics to see if you will blend into most maps. Now depending on if the map is gently snowing of a full-blown blizzard you can have improved visibility to extremely low visibility. Personally, I think there should be a random blizzard or two that happen per match and then they subside after a minute or two. You could give players a tall tale sign that the blizzard will be happening soon by the winds picking up (predator) and the tech dude informing the fireteam. This will cause players to plan around the blizzard since that is the time where the predator is most likely to strike. The blizzard would greatly reduce all players’ vision as well as sound queues. You can make it so the blizzard even slows all players and causes the predator’s cloak to malfunction if you really wanted.
Another Map you could add to the game is a city map from Predator 2. You can make it a part of the town that isn’t highly active. If you really wanted you can make the fireteam look like gangsters or mercenaries for hire with a map-specific cosmetic customization option. The map can have the predator use lamp posts, billboards, telephone posts, and the sides/edges of certain buildings as predicore options. Now, part of this map can take place in streets and back alleys but there will be parts where they have to go into a multistory building. Now the buildings can have destructible windows to make it so the players can break them with weapons and jump out of them. This will mean that pushback weapons will be extremely deadly as you can knock players off. The close quarters of the building will add a way for the fireteam to have a higher chance of killing the predator or the predator can AOE the fireteam since they are so bunched up.
Now, another map you can add is a mountainous map that could take place in Northern America or Canada where they have evergreen forests and tons of fog. This map will have a secret OWLF facility that the fireteam later infiltrates for mission objectives. Now since the trees won’t be as extravagant as the current maps trees you can have the predator cling to the sides of the trees or have very little wiggle room. To counterbalance the lack of moving from long branch to long branch you will have tons of trees to bounce to and for cover. Now you can add fog to the map to make it a little harder for the fireteam to see as well as the predator without using heat visor.
FInally the final map idea. The final map idea I had was something that I know most people wanted but with the announcement of Alien: Fireteam I do not know if this will happen. You can have the map take place in a temple (snow or jungle) or starship. This map will contain xenomorphs instead of regular unfriendly AI. The fireteam can be skinned as Colonial Marines if on a starship via cosmetic option. This can give players some AVP action they wanted since Alien Vs Predator (2010) came out. You can have part of the map covered in the xenomorph building structure and leave the rest of the map normal or destroyed. The addition of xenomorphs will greatly increase the urgency that both parties will have to complete their objectives since the xenomorphs could patrol areas or actively hunt down players. The death of a xenomorph will cause players damage if they are too close to the blood splatter. You can also have it so that a dead xenomorph causes the ground its body is on to deal damage over a small timeframe. You could also add an alternative objective for both parties to take down the predalien or queen on the map if the players do this it will reward them greatly since they will be a boss/miniboss.
Now to address the map themes you can add a customization option to give players the ability to have certain skins on certain maps. There is already a ton of loadouts in the game and I for sure only really use 4 of them so adding in new map-specific cosmetics so you can better blend into the map will make good use of all the loadouts in the game. They can even add them into field crates so you can have tons of customization for all characters.
