It's my opinion that this is the best field in Calgary. The staff are helpful and easy to talk to. They have 4500 psi fills on air. The 'dead-boxes' are completely netted so it's safe to remove your mask. They are on the fields so you don't spend half the day walking to them once you are out.
The fields have good variety and are the biggest in the area. The trench field is an intense experience. It's unique to most paintball fields I have played on. The town field is designed like a real town, not like a speedball field with buildings. There are dozens of small buildings and 3 large ones. One of the big buildings is a 2 story structure. There are also walls, towers with walkways and numerous bunkers. The field is ringed by woods so it provides avenues to approach. The hill field is big and very woodsy with lots of area to flank and is one of my favourite fields. The castle field is also a large woodsball field with 3 structures spread out in a hilly forest.
Where Rampage has it over their competion is their monthly Big Games. They are designed to have a Milsim feel to them. The scenarios are designed around an objective. They have secret objectives that only the team knows and can challenging to complete ie prisoner escorts, find a down pilot and return him to an extraction area, demolishion a certain target. There are medics, special forces, generals to make the games more interesting.The players are 90+ with a good mix of gun owners and renters. Everyone is trying to complete the team objectives or preventing the other team from completing theirs. The games are all based on points. No one seems to really care about the final score as they are having too much fun playing.
The only thing I think holds the field back is they are the priciest in the area. I really think you get what you pay for. You can see that Brian puts the $$$ back into the field.
If you haven't played here before I suggest you come out and if you are looking for a Milsim experience try one of the Big Games. You won't be disappointed.
