Door Kickers PC

A great little tactical game, with plenty of good mods (That sort of work). A little rough around the edges but I love trying to do the mission challenges.

Great game to pass the time.
Starts off easy and builds up into more complex missions. Plenty of videos with tips online if you search.
Offers something a little different to usual shooter/top down shooter.
Customisable loadouts so you can try different tactics.
Quite a lot of campaign missions to play through, even more single missions to do and there is a random mission generator and you can download more missions via the game.
Well worth buying for a couple of quid.
