What extra bits and pieces do you find yourself always adding to your missions?
Here's a few I keep coming back to after building many many missions.
Obviously VCOM AI some prefer ASR AI but personally after watching VCOM driven units in Zeus for longer than I care to admit, it's hard to go past VCOM for AI improvements.
I use rafael09ed's Survivable crashes script in just about every one of my missions. Getting shot down behind enemy lines, or seeing one of your pilots go down and knowing that it's actually worth sending an element to rescue them adds a lot to a mission.
I also use phronk's Simple IED Script . I've found ALiVE's insurgency takes a while before IED's become a factor, so using phronks script just to sprinkle a few across the map keeps the players on their toes from the start of deployment.
If you're not using musucra's Guilt and Remembrance mod (requires ACE) then I really think you're missing out. Designed with ALiVE in mind it creates a mechanic around the death of civilians. As well as the loss of rep you get from ALiVE, Guilt and Remembrance can be set up to allow you to return that dead body to the deceased family or simply bury the body outside of town to reduce the effects of your civilian slaying. Event handlers allow you to customize the effects your actions have, and any punishments you want to dish out for potential war crimes.
Finally this one might not appeal to everyone but I put off using it for ages and regret doing so, and that's Jokoho482 and LAxemann's Suppress mod. No more can your players just stand there and go toe to toe with the enemy, the suppression effects while "gamey" do a great job, and will have your players looking to break contact and find cover rather than trying to rambo assault the enemy.
Has anyone else got any scripts or mods they always find themselves adding to missions?
